work of an enzyme
This is to show what occurs to the food that we consume on a daily basis.One of the process that bring growth in mammals (human beings) is the intake of diffrent types of food. And this food that we eat cannot generate growth by itself but it has to work with glands, hormones, enzymes etc. With this report we will focus on how enzymes reacts with the food or whatever we take in.
What is an enzyme? An enzymes is a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. It is a biochemical catalyst that allow chemical reaction to take place, it is a functional protein that regulates various metabolic pathway of the body.
On this note what is a catalyst? A catalyst is
When chemical biuret reagent reacts with protein it turns up purple blue in the presence of undigested protein and lavender pink in the presence of amino acids.
Protein digestion occured Tube.If you add egg white pr albumin with sodium hydroxide the color of the mixture after adding biuret reagent the result is a light pinkish purple which shows protein digestion.
In Tube 4 there was not a protein digestion the egg white plus HCl after adding biuret reagent gives a clear color.
Enzyme catalyzed chemical reaction with greatest efficiency within a narrow range of pH.The effect of pH on protein digestion with pepsin is a protein digestion enzyme in (gastric juice) operate between a low pH range. The reason being most enzymes in the human body work best within a narrow range of temperature near 40 degrees celsius.

This causes the lipase to clump together and form large fat “globules” in the small intestine. In this form it is nearly impossible for the enzyme pancreatic lipase to catalyse the breakdown of lipase into monoglycerides and free fatty acid because it has only a small surface area on which area to work pancreatic lipase. The first step in lipase digestion is to breakup this large fat globule into smaller piece, a process called

.2 ml enzyme 1 ml of 0.0003M DPIP was added to each tube, noting the time the addition was made. A dropper full of cooking oil was added to cover the surface of the solution. The time taken for the blue colour to disappear or become very faint, was recorded. This procedure was repeated for tubes 2 and 3
Enzymes are biological catalysts, which are proteins that help speed up chemical reactions. Enzymes use reactants, known as the substrates, and are converted into products. Through this chemical reaction, the enzyme itself is not consumed and can be used over and over again for future chemical reactions, but with the same substrate and product formed. Enzymes usually only convert specific substrates into products. Substrates bind to the region of an enzyme called the active site to form the enzyme/substrate complex. Then this becomes the enzyme/products complex, and then the products leave the enzyme. The activity of enzymes can be altered based on a couple of factors. Factors include pH, temperature and others. These factors, if they become
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.
Enzymes are biological catalysts - catalysts are substances that increase the rate of chemical reactions without being altered itself. Enzymes are also proteins that fold into complex shapes that allow smaller molecules to fit into them. The place where these substrate molecules fit is called the active site. The active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction. The active site consists of residues that form temporary bonds with the substrate and residues that catalyse a reaction of that substrate. (Clark, 2016)
The sphincter at the conclusion of the stomach recognizes as the pyloric sphincter that controls the food from entering the small intestines. As the food enters the stomach, the chemical digestion continues by other enzymes, acid, and bile that released during this process. Different enzymes work on different food components. The stomach has three primary functions the storage of food, the mixing of food and controlled emptying of food into the small intestines. The chemical digestion occurrence within the stomach is mainly from the enzymes released in the stomach. Pepsin is the enzyme that begins the disintegrate of protein. The stomach also discharges gastric lipids that act on butterfat. Tributyrinase anatomizes the fat within the cheese and the turkey and bread of the sandwich into tributyrin. The tributyrin undergoes more chemical reaction transform it into glycerol and fatty acids. The turkey, cheese lettuce and bread are further broken down by pancreatic amylase digesting the starches breaking them down into disaccharides, lactose, sucrose, and maltose. These are further broken down into monosaccharides, lactose to glucose and galactose. Sucrase to broken down to glucose and fructose. Maltase breaks down to maltose to form two molecules of glucose. The protein in the turkey and cheese is broken down by Trypsin and polypeptides to dipeptides. A chemical reaction in body dilapidated
Enzymes have the ability to act on a small group of chemically similar substances. Enzymes are very specific, in the sense that each enzyme is limited to interact with only one set of reactants; the reactants are referred to as substrates. Substrates of an enzyme are the chemicals altered by enzyme-catalysed reactions. The extreme specific nature of enzymes are because of the complicated three-dimensional shape, which is due to the particular way the amino acid chain of proteins folds.
Enzymes as mentioned before help speed up reactions, they generally work by bonding to a substrate, this bonding occurs at the active site. This link then forms a different molecule which will benefit its respective process. Every enzyme has its own optimum pH level to work under, if too low the enzyme will be very slow. However if too high the enzyme will then denature and be obsolete. This is why it is important to know the optimum pH level for whatev...
The Advantages and Disadvantages of Using Enzymes in Medicine and Industry What is an enzyme? = == ==
In this lab, it was determined how the rate of an enzyme-catalyzed reaction is affected by physical factors such as enzyme concentration, temperature, and substrate concentration affect. The question of what factors influence enzyme activity can be answered by the results of peroxidase activity and its relation to temperature and whether or not hydroxylamine causes a reaction change with enzyme activity. An enzyme is a protein produced by a living organism that serves as a biological catalyst. A catalyst is a substance that speeds up the rate of a chemical reaction and does so by lowering the activation energy of a reaction. With that energy reactants are brought together so that products can be formed.

Enzymes are protein molecules that are made by organisms to catalyze reactions. Typically, enzymes speeds up the rate of the reaction within cells. Enzymes are primarily important to living organisms because it helps with metabolism and the digestive system. For example, enzymes can break larger molecules into smaller molecules to help the body absorb the smaller pieces faster. In addition, some enzyme molecules bind molecules together. However, the initial purpose of the enzyme is to speed up reactions for a certain reason because they are “highly selective catalysts” (Castro J. 2014). In other words, an enzyme is a catalyst, which is a substance that increases the rate of a reaction without undergoing changes. Moreover, enzymes work with
