AP Enzymes

Any INORGANIC non-protein molecule or ion that is required for the proper functioning of an enzyme

Any ORGANIC non-protein molecule or ion that is required for the proper functioning of an enzyme

When an inhibitor binds to the active site of an enzyme and blocks the substrate from binding there

The part of an enzyme where the chemical reaction occurs

A form of allosteric regulation that can amplify enzyme activity

As the enzyme and substrate come together, their interaction causes a mild shift in the enzyme’s structure that confirms an ideal

binding arrangement between the enzyme and the transition state of the substrate. This is known as the _______ theory of enzyme

function.

• ideal state

• institutional

• induced fit

• transitional

The image illustrates which property of enzymes?

• Enzymes change the free energy of the reaction.

• Enzymes make a reaction exergonic.

• Enzymes lower the activation energy of the reaction.

• Enzymes make the reaction occur spontaneously.

The diagram shows

• competitive inhibition

• allosteric inhibition

• feedback inhibition

• induced fit model
