______ inhibitor binds to a site on the enzyme that is not the active site.

An allosteric inhibitor does which of the following? a. Binds to an enzyme away from the active site and changes the conformation of the active site, increasing its affinity for substrate binding, b. Binds to the active site and blocks it from binding substrate, c. Binds to an enzyme away from the active site and changes the conformation of the active site, decreasing its affinity for the substrate, d. Binds directly to the active site and mimics the substrate.

The random movement of molecules caused by their kinetic energy is called

Determine whether the scenario pertains to the anaerobic or aerobic breakdown of glucose

Occurs when plenty of oxygen is available in the muscle

Adding a catalyst to a chemical reaction will (1) lower the activation energy needed (2) lower the potential energy of the reactants (3) increase the activation energy (4) increase the potential energy of the reactants

What is the function of the lacZ gene?

a. This gene encodes an enzyme, galactoside permease, which transports lactose into the cell.

b. This gene encodes an enzyme, b-galactosidase, that cleaves lactose into two glucose molecules.

c. This gene encodes the repressor of the lac operon.

d. This gene encodes an enzyme, b-galactosidase, which cleaves lactose into glucose and galactose.

How are allosteric enzymes different from other enzymes?
