Enzymes

Enzymes

Enzymes. Most enzymes are globular proteins. Active site: the region of an enzyme surface to which a specific set of substrates binds. Substrate : ( the reactant ) a molecule upon which an enzyme acts. A substrate molecule must fit precisely into an active site.

What are enzymes made of?

What are enzymes made of?

What are enzymes made of?. Enzymes are protein molecules, and so are made up of amino acids . Most enzymes contain between 100 and 1,000 amino acids. These amino acids are joined together in a long chain, which is folded to produce a unique 3D structure. Why is shape important?.

Enzymes

Enzymes

Enzymes. Enzymes are proteins that speed up biological chemical reactions. without themselves being used up in the process. Thus they are biological catalysts. They can be used over and over and over again. All chemical reactions involve a change in energy.
