Enzymes are proteins that are macromolecule biological catalysts, catalysts are enzymes that speed up the process of a chemical reaction. Although not all enzymes are proteins to tell if something is an enzyme it will end in -ase and most sugars end in -ose. The process that occurs within every living organisms is a chemical reaction. Before a chemical reaction begins the enzymes need to go through activation energy which is energy needed to get a reaction started. During the chemical reaction substrates enter the active site and create a lock and key fit within the enzyme, the enzyme converts the substrates into products. It then releases the substrates that were turned into products and finishes off with a product(s). As you can see in the …show more content…
In the pancreas the enzyme is trypsin and the substrate is protein and the product is peptides and amino acids. This enzyme is important for the digestion of proteins. It is one of the three digestive proteins the other two are pepsin and chymotrypsin. Together they break down protein molecules into peptides and amino acids. The macromolecule class that this enzyme breaks down is proteins. The chemical reaction of trypsin is first the enzyme of this chemical reaction is trypsin and the reactant/ substrate is protein, so the protein has a lock and key fit with the trypsin enzyme and then the protein converts into products which are peptides and amino acid and then the products released from the enzyme. In the salivary glands the enzyme is salivary amylase and the substrate is starch and the products are maltose. This enzyme is found in the saliva of humans and animals that help the predigestion of starches and it is important because it breaks down the starch when you eat food and converts it into smaller carbohydrates (maltose), carbohydrates are an important source of energy in the body. This macromolecule class that this enzyme breaks down is …show more content…
The chemical reaction for the salivary amylase is the substrate is starch and the enzyme is the salivary amylase the starch has a lock and key fit with the salivary amylase and then the starch converts into products which is maltose and then the product releases. In the stomach the enzyme is pepsin and the substrate is protein and the product is peptides and amino acids. This enzyme is an endopeptidase, which is activated by gastric juice it is important because it begins the digestion of ingested proteins. Pepsin is one enzyme that works best in all ph levels since it is located in the stomach. The macromolecule class of this enzyme is proteins. The chemical reaction for pepsin is that pepsin is the enzyme and the reactant/ substrate is protein and the pepsin and the protein have a lock and key fit and then the protein converts into products which are peptides and amino acids then the products release. In the small intestine the enzyme is peptidases and the substrate is peptides and the products are amino acids, a lack of peptidase can lead to illnesses this enzyme is important because it breaks down proteins and it provides organisms with the necessary amino acids. The macromolecule class of this enzyme is
Living organisms undergo chemical reactions with the help of unique proteins known as enzymes. Enzymes significantly assist in these processes by accelerating the rate of reaction in order to maintain life in the organism. Without enzymes, an organism would not be able to survive as long, because its chemical reactions would be too slow to prolong life. The properties and functions of enzymes during chemical reactions can help analyze the activity of the specific enzyme catalase, which can be found in bovine liver and yeast. Our hypothesis regarding enzyme activity is that the aspects of biology and environmental factors contribute to the different enzyme activities between bovine liver and yeast.
== Amylase is an enzyme found in our bodies, which digest starch into
Proteins are one of the main building blocks of the body. They are required for the structure, function, and regulation of the body’s tissues and organs. Even smaller units create proteins; these are called amino acids. There are twenty different types of amino acids, and all twenty are configured in many different chains and sequences, producing differing protein structures and functions. An enzyme is a specialized protein that participates in chemical reactions where they serve as catalysts to speed up said reactions, or reduce the energy of activation, noted as Ea (Mader & Windelspecht).
Background information:. Enzyme Enzymes are protein molecules that act as the biological catalysts. A Catalyst is a molecule which can speed up chemical reactions but remains unchanged at the end of the reaction. Enzymes catalyze most of the metabolic reactions that take place within a living organism. They speed up the metabolic reactions by lowering the amount of energy.
The pancreas can be divided into two sections when studying the histology. The pancreas has exocrine and endocrine functions, each with unique cell types. The exocrine pancreas serves to secrete digestive enzymes into the duodenum. Some of the specific enzymes and secreted substances are Proteases, lipase, amylase, bicarbonate, and water (Bowen, “Exocrine Secretions”). These enzymes are used to break down protein, fat, and carbohydrates respectively. The bicarbonate simply act as an acid buffer to prevent damage of the small intestine as the stomach acid must be neutralized. The enzymes are created in acinar cells and the bicarbonate is synthesized in epithelial cells surrounding pancreatic ducts (Bowen “Exocrine
Imagine you are eating a sandwich containing wheat bread, ham, lettuce, and Swiss cheese. Do you ever wonder where the nutrients go from all of the previous listed ingredients? Well, when a bite of this sandwich is taken, the mouth produces a saliva enzyme called amylase. This enzyme immediately goes to work by breaking down the carbohydrates that are in the bread. Once, the bite is completely chewed, the contents then are swallowed and go down the esophagus and begin to head towards the upper esophageal sphincter and the is involuntarily pushed towards the stomach. The next passage for the sandwich is to go through the lower esophageal sphincter; which transports the sandwich into the stomach.

Enzymes are found inside cells (intracellular) and outside cells (extra cellular). Intracellular enzymes are for example, those that control metabolism while extra cellular enzymes are for example, gut digestive juices and the enzymes secreted by bacteria, which digest their food outside the body then reabsorb the products. Enzymes work on particular organic chemicals, these are called substrates. So in effect food is the substrate of digestive enzymes. Each enzyme is specific to one or a group of particular substrates.
How the protein digestion starts is within the stomach. It starts as pepsinogen secreted by the chief cells and quickly activated to pepsin. Pepsin is found functioning optimally within the stomach at its acidic pH range of 1.5-2.5.
Now the Cheetos have entered the stomach. The process of breaking down carbohydrates has already begun in the mouth and now more chemical and mechanical digestion will take place in the stomach. Once the bolus has entered the stomach, it mixes with gastric juice, starts protein digestion, and absorbs a limited amount. Here the chief cells secrete the inactive enzyme pepsinogen and the parietal calls secrete hydrochloric acid. When mixed together, they create pepsin. The pepsin works to breakdown the two grams of protein present in the Cheetos. Hormones are also present in the stomach and aid in the digestion process. The hormone, gastrin, increases the secretory activity of gastric glands. In the stomach, some salt from the Cheetos is absorbed through the wall. The Cheetos that entered the stomach has no...
According to the graph on amylase activity at various enzyme concentration (graph 1), the increase of enzyme dilution results in a slower decrease of amylose percentage. Looking at the graph, the amylose percentage decreases at a fast rate with the undiluted enzyme. However, the enzyme dilution with a concentration of 1:3 decreased at a slow rate over time. Additionally, the higher the enzyme dilution, the higher the amylose percentage. For example, in the graph it can be seen that the enzyme dilution with a 1:9 concentration increased over time. However, there is a drastic increase after four minutes, but this is most likely a result of the error that was encountered during the experiment. The undiluted enzyme and the enzyme dilution had a low amylose percentage because there was high enzyme activity. Also, there was an increase in amylose percentage with the enzyme dilution with a 1: 9 concentrations because there was low enzyme activity.
Enzymes are types of proteins that work as a substance to help speed up a chemical reaction (Madar & Windelspecht, 104). There are three factors that help enzyme activity increase in speed. The three factors that speed up the activity of enzymes are concentration, an increase in temperature, and a preferred pH environment. Whether or not the reaction continues to move forward is not up to the enzyme, instead the reaction is dependent on a reaction’s free energy. These enzymatic reactions have reactants referred to as substrates. Enzymes do much more than create substrates; enzymes actually work with the substrate in a reaction (Madar &Windelspecht, 106). For reactions in a cell it is important that a specific enzyme is present during the process. For example, lactase must be able to collaborate with lactose in order to break it down (Madar & Windelspecht, 105).
Enzymes are biological catalysts that increase the rate of chemical reactions within the cells without any change at the end (Palmer, 1991). In the absence of enzymes, most biological process might not occur. The purpose of an enzyme is to allow the cell carry out its functions in time. As the structure of most biological molecules play a major role in their function, the three dimensional structure of an enzyme is responsible for its catalytic activities. Therefore, enzymes are proteins made of amino acids. This essay further points out the features of enzymes that accounts for why, they are made of proteins, not other macromolecules.
The exocrine function of the pancreas is that it produces enzymes that aids in the digestion of food. There are three important enzymes that are crucial in helping with digestion. The first digestive enzyme is amylase. Amylase function is to break down carbohydrates. The amylase enzyme is made in two places: the cells in the digestive tract that produces saliva and the main one specifically found in the pancreas that are called the pancreatic amylase (Marie, Joanne; Media Demand, “What Are the Functions of Amylase, Protease and Lipase Digestive Enzymes”). The amylase in the pancreas passes through the pancreatic duct to the small intestines. This amylase in the pancreas completes the process of digestion of carbohydrates. Consequently, this leads to the production of glucose that gets absorbed into the bloodstream and gets carried throughout the body. The next enzyme that aids in digestion of food is protease. While amylase breaks down carbohydrates, protease breaks down protein. Protease breaks down protein into the building block form of amino acids. The three main proteases that it produces are: pepsin, trypsin and chymotrypsin (Marie, Joanne; Media Demand, “What Are the Functions of Amylase, Protease and Lipase Digestive Enzymes”). Pepsin does not occur in the pancreas but it is the catalysis in starting the digestion of proteins. Trypsin and chymotrypsin are the two proteases that occur in
As you chew, the salivary glandes release a liquid called saliva. Saliva contains mucous which moistens the food and causes less friction when the bolus passes the esophagus and into the stomach and an enzyme, called Amylase, which is used to breakdown carbohydrates. The
