A Biological Catalyst Essay

Enzyme is an essential concept in biology; they act as catalysts, speeding up chemical reactions by lowering the activation energy. According to the Lock & Key model, a specific substrate joins with a specific enzyme at the active site, to form the enzyme-substrate complex; this brings the reactants closer together to facilitate chemical reactions (Ophardt).

Enzymes are proteins that act as catalysts during a biochemical process. Catalysts are non-changing enzymes that can increase or decrease activation energy to accelerate or slow down a biochemical reaction without using additional energy.

3. Cells use enzymes as biological catalysts to increase or accelerate the rate of reactions, such as those in photosynthesis or glycolysis. This allows reactions to occur under conditions that sustain life.

Enzymes are biological catalyst, meaning that it increases the rate of reaction without contributing to the reaction or being used up. The amount in which the enzyme increases the rate of reaction is known as CATALYTIC ACTIVITY. An example of an enzyme is amylase, which convert starch into maltose (amylase is found in saliva). Furthermore, enzymes have specific jobs in which allow control different chemical reactions, hence why there are thousands of different enzymes in the human body.

In order to understand how enzymes work, it is important to know what a catalyst is. A catalyst is a substance that enhances the rate of a chemical reaction without undergoing any irreversible chemical change at the end of the reaction (Chemicool). An enzyme is a protein that functions as a catalyst during chemical reactions. In order for chemical reactions to occur, a certain amount of energy in what is known as the activation

Enzymes are molecular catalysts which are needed in biological processes. Enzymes are catalyzed in a

The lock and key theory is a shaped substance that can fit into the active site of the enzyme, for example a lock which would be the enzyme, and key which would be the substrate (Chemistry.elmhurst.edu, 2016). The induced fit theory determines the final shape of the enzyme as the enzyme is partially flexible (Chemistry.elmhurst.edu, 2016).

Biological catalyst have enzymes which contains soluble proteins that can increase the speed of the chemical reactions in cells. The relationship between enzymes and catalysts is that the enzymes will increase the rate of speed in the chemical reactions that happen within and outside of the living cells.

The biological definition of an enzyme is, a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. Based on research in genetics, it can be concluded that there are around 25,000 enzymes. From these enzymes, only 5,000 have been characterized so there is a great deal still to discover. Organic reactions in the body tend to be very slow, so in order to account for the slowness of these reactions, enzymes are needed to be a catalyst in these reactions to speed up the process. Enzymes are binding proteins. They bind with certain substrates to create products.

In biological reactions, enzymes function as catalysts to speed up the rate of chemical reactions by lowering the activation energy without being consumed.

An enzyme is a globular protein that serves as a catalyst for biochemical reactions. Enzymes lower the activation energy because they stress the bonds in the substrates. A substrate is the reactant. When a substrate locks into the active site of an enzyme, a reaction is then catalyzed and the products of the reaction are released.

Proteins that are produced by living cells are known as enzymes. Enzymes are catalysts – they increase the rate of a chemical reaction by lowering the activation energy. The enzyme has an active site to which the substrate, or substance acted upon, binds, forming an enzyme-substrate complex. This active site, which is determined by the sequence of amino acids, is specific to which substrate it binds to, known as the lock-and-key theory. (This theory has been modified to the induced fit theory, which states that an enzyme will slightly change shape to accommodate a substrate.) The enzyme is not used up in the reaction; rather, it can be reused to keep converting substrate to products.

Enzymes catalyse the macromolecular biologic process produced from living molecules, or cells. They create, accelerate or catalyse a chemical reaction between at least one other molecule, this is known as to synthesise. At the preenzyme process the target molecule is known as a substrate, once converted by the enzyme the changed molecule is referred to as the product. In order to sustain life all metabolic processes in the cell require enzymes in order to metabolise at a fast enough rate. The metabolic routefinders in a cell are determined by which set of enzymes are present in its makeup.

Enzymes are proteins that act as catalysts within living cells. Catalyst increase the rate at which chemical reactions occur without being consumed or permanently altered themselves. A chemical reaction is a process that converts one or more substances (known as reagents, reactants, or substrates) to another type of substance (the product). As a catalyst, an enzyme can facilitate the same chemical reaction over and over again.

The amylase enzyme is produced by your pancreas gland to help make saliva. Pancreatic amylase completes digestion of carbohydrate, producing glucose, a small molecule that is absorbed into your blood and carried throughout your body (Marie 1). The amount of time it takes an enzyme to break down starch into sugars depends on the conditions of the solution. If the pH is too high or too low the enzyme won’t break the starch down. If the temperature is different than the specific circumstances of the enzyme, then either it will take a longer amount of time, or it will not break the starch down at all.
