Unit 8 Metabolism

Question 1

Inhibitors

Answer 1

Molecules that slow down the rate of enzyme activity.

Question 2

Competitive Inhibitors

Answer 2

Competitive Inhibitors bind to the active site of the enzyme which blocks the substrate from binding to the active site. The inhibitors are chemically similar to the substrate.

Question 3

Non Competitive Inhibitors

Answer 3

Non competitive Inhibitors binds to the allosteric site of an enzyme, this changes the shape of the active site preventing the substrate from binding.

Question 4

How to increase enzymes activity with competitive inhibitors

Answer 4

Increasing the substrate concentration will increase the enzyme activity because there will be a greater chance that a substrate will bind to the enzyme rather than the inhibitor. The inhibitor is in direct competition with the substrate.
