Unit 2 exam review

lyases

The class of enzyme that catalyzes addition of a group to a double bond is

oxidoreductases

The class of enzyme that catalyzes reduction reactions is

cofactors

Nonprotein helper factors that bind an enzyme and assist in its catalysis are called

carboxyl group transfer

Biotin is an enzyme cofactor that promotes________, a type of reaction not easily accommodated by proteins by themselves.

active site

The location within an enzyme where reactant(s) bind and the reaction is catalyzed is called the

The image at right shows which of the following aspects of enzymatic catalysis?

• a favorable interaction of the substrate with the enzyme active site

• allosteric activation of the enzyme

• the lock and key model of catalysis

• the induced fit model of catalysis

• the formation of the catalytically competent ES complex
