Enzymes are known as biological catalysts. (Ahmed) These enzymes bind to substrates.

They have specific substrates that they have to bind to. The are where enzymes bind are called

an active site. The job that a catalyst holds is to speed up the reaction. All this is only possible

through chemical reaction. The input of energy given to chemical reactions is called activation

energy. This is the process is what pushes the reaction to happen. Enzymes acts like a catalyst

that speeds up without being consumed by the reaction. Enzymes are a huge part of the body

that speeds up the chemical process, they are needed otherwise our bodies would not be able to

Another essential part of an enzyme is its substrate. These are needed in order for them

to act on. The specific area where the enzyme binds with the substrate is called an activation

site. The activation site is where the reaction speed up occurs. The binding reaction is divided

into three main sections. These reactions are called forward reaction, reverse reaction, and at

equilibrium. These illustrat...

Catalysts and Chemical Reaction Essay

- CATALYSTS Catalysts are substances used to increase or decrease the rate of a chemical reaction. A catalyst is a substance which alters the rate of a chemical reaction but is chemically unchanged at the end of the reaction.The word catalysts originally comes from the word Catalysis meaning the change in rate of a chemical reaction. Catalysts unlike other substances, may participate in many chemical transformations but never consumed by the reaction itself. This means that, when a catalyst is added to two substances to increase the reaction rate between them, the catalyst isn't consumed and may be used again.([3]"Chem4Kids.com: Reactions: Catalysts and Inhibitors.") For example, the decompos...   [tags: Definition, Function, Environmental Effects]

Catalysts Essay

- Catalysts speed up the rate of reaction and remain chemically unchanged or being used up in the process, and are widely used in industry. Enzymes are biological catalysts made up of proteins, and can be used a lot in industry since they operate best close to room temperature and pressure which can be maintained in industrial processes. Catalysts will speed up rate of reaction and can also be used to change properties of a product to increase it’s usefulness – it can turn light, bendy poly(ethene) into a more dense and less flexible material with a higher melting point....   [tags: Chemistry ]

The Effects and Influences of Enzymes Essay examples

- ... the enzymes may not be able to function properly if the environment around them undergoes a change. Globular shaped, enzymes are said to have a gap, which is where all the activity supposedly takes place. This site is known as the active site and is the source of all enzyme related reactions. All enzymes have this active site irrespective of whether they are inside the cells (intracellular enzymes) or outside (extracellular enzymes). Some examples of extracellular enzymes include those found in the digestive tract are released when necessary because their activity takes place outside the cells....   [tags: catalyst, reaction, conditions]

Essay on Enzymes And The Enzyme Substrate Complex

- As globular proteins, enzymes have a specific three-dimensional shape which is determined by their sequence of amino acids. This specific tertiary structure is held together by ionic bonds, hydrogen bonds and disulphide bridges. Despite their generally large size, enzyme molecules have a small region that is functional, known as; the active site. The substrate molecule is held within the active site by bonds that temporarily form between the R groups of the amino acids of the active site and groups on the substrate molecule....   [tags: Metabolism, Enzyme, Adenosine triphosphate]

Essay about Testing the Rate of Reaction for Catalysts

- Testing the Rate of Reaction for Catalysts Introduction Enzymes are produced in cells. They are proteins that act as catalysts. Catalysts are chemical substances that speed up reactions but do not get used up during the reaction. A single enzyme can be used as many times over. An example of how an enzyme molecule might join two other molecules together and form a more complicated substance is shown below. Reactions in which large molecules are created from small molecules are called anabolic reactions....   [tags: Papers]

Essay on Background On Enzymes

- Background On Enzymes Enzymes are biological catalysts. They speed up the chemical reactions which go on inside living things. Without enzymes reactions would be so slow that eventually life would grind to a halt. There are many different types of enzymes and each of them is extremely efficient at doing their job. For example, some of the reactions which take place in our cells, e.g. the liver, produce a by-product called hydrogen peroxide. Hydrogen peroxide is very poisonous so it must be gotten rid very quickly....   [tags: Papers]

Essay on Enzymes

- Enzymes Enzymes are biological catalysts. A catalyst is defined as a substance that increases the rate of a chemical reaction without itself undergoing any permanentchange. Enzymes do precisely this in living things. Without them, the rate of the reactions would be so slow as to cause serious, if not fatal, damage. Enzymes have two main functions: To act as highly specific catalysts, and also to provide a way of controlling reactions, the amount of enzyme determines how quickly the reaction can proceed....   [tags: Papers]

Enzymes Essay

- Enzymes Enzymes are biological catalysts that carry out thousands of chemical reactions that occur in living cells. They are a class of proteins that have a unique three dimensional structure that allows it to bind with a specific substrate to facilitate a reaction. Many biological reactions will not occur spontaneously in the cell; there is simply not enough energy for the reaction to take place. Enzymes make these reactions possible by lowering the reactionÂ’s activation energy....   [tags: Papers]

Enzymes Experiment Essay

- Enzymes Experiment Introduction Enzymes are biological catalysts that promote some of the thousands of chemical reactions that occur in living cells. They are large molecules that have a unique three-dimensional structure that allows it to react with a specific substrate. It is hypothesized that pH levels out of the normal range found in cells would denature the enzyme, slowing the enzyme's reaction rates. Hydrogen Peroxide (H2O2) is a poisonous chemical that is continually being formed as a byproduct of reactions in peroxisomes of living cells....   [tags: Papers]

Enzymes Essay

- Enzymes are presented in many different shapes and sizes because form fits function. Enzymes play an active role in everyday life, in every living organism. What all enzymes have in common is that they are proteins meant to speed up chemical reactions because without them reactions would occur at an extremely slow rate. This would be a conflict for every living thing which is why enzymes are so important. Enzymes are defined as “a protein formed by the body that acts as a catalyst to cause a certain desired reaction” (1)....   [tags: Scientific Research ]
