Enzymes are important in cell's chemical reaction. describe what a enzyme's role in chemical reactions is and explain what an enzyme does. the following key words may you structure your response: active site, enzyme-substrate complex, and activation energy. try to

Enzymes are proteins that catalyze chemical reactions that occur in living things. They accelerate the speed of reactions, which contributes to metabolism. Without enzymes, many reactions would be extremely slow.

Explanation:

Each enzyme is specific to a type of reaction. That is, they only act on a given compound and always perform the same type of reaction. The compound on which the enzyme acts is generally referred to as substrate. The great enzyme-substrate specificity is related to the three-dimensional form of both.

The enzyme binds to a substrate molecule in a specific region called a binding site. For this, both the enzyme and the substrate undergo conformation change for the socket.

They fit perfectly like keys in locks. We call this behavior the Key-Lock Theory.

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.

3. a complex molecule containing he genetic code is dna or deoxyribonucleic acid.

4. an enzyme refers to a molecule of protein, which is unique in accelerating up a particular chemical reaction in the biological systems.

5. nucleic acid refers to an sequence of sugars, phosphates, and nitrogenous bases, for example, dna and rna.

6. a protein refers to a large, composite organic molecule comprising of a huge number of amino acids associated together with the of peptide bonds.

7. rna refers to a nucleic acid that takes part in the production of proteins.

8. substrate refers to a compound, which takes part in a chemical reaction, and is chemically modified by the reaction.
