AP Bio Enzyme Rates

In noncompetitive inhibition

• the inhibitor binds to a different part of the enzyme causing a change of shape.

• the inhibitor binds to the active site of the enzyme causing a change of shape

• the substrate bind to the active site.

• the substrate and inhibitor are the same shape.

The induced fit model of the enzyme-substrate interaction can possibly overcome competitive inhibition by

• increasing concentration of the substrate.

• decreasing concentration of the substrate.

• increasing the concentration of the enzyme.

• changing the active site.

How do enzymes speed up chemical reaction?

• Increasing activation energy

• Decreasing activation energy

• Increasing deactivation energy

• Decreasing deactivation energy

Enzymes need certain environmental conditions in order to function properly.  What happens when enzymes are heated to a high temperature?

• they die

• they denature

• they change their amino acid sequence

• they work better

When a molecule can occupy the same active site as the substrate, a situation called __________________ can result

• Competitive lnhibition

• Allosteric Regulation

• Non-Competitive Inhibition

• Feedback Inhibition

Which statement explains the effect of an inhibitor on an enzyme?

• A substrate will be able to bond with the enzyme.

• The enzyme will likely be attacked by immune cells.

• The enzyme will be unable to produce more enzymes.

• A substrate will be unable to attach to the enzyme.

What type of reaction is occurring in this graph?

• endergonic

• exergonic

• unable to determine

A receptor site that a molecule can bind to that changes the shape of the active site is called a(n):

• Allosteric Site

• Active Site

• Activation site

• Reactant site

What type of molecule is responsible for changing glucose into the numerous other molecules in the process of glycolysis?

• Carbohydrates

• Enzymes

• Nucleic acids

• Proteins

• Lipids

ADP is converted into ATP by...

• An enzyme removing a phosphate group.

• An enzyme adding a phosphate group.

• An enzyme changing the charge of ADP.

• The spontaneous addition of a phosphate group.
