Enzyme

Question 1

Explain why maltase:
only breaks down maltose
allows this reaction to take place at low temp

Answer 1

1. The tertiary structure of the enzyme means 2. Active site is complementary to maltose 3. Enzyme is a catalyst which 4. Lowers activation energy 5. By forming enzyme-substrate complex;

Question 2

Describe competitive and non-competitive inhibition of an enzyme

Answer 2

1. Inhibitors prevent the formation of ES
   complex; 2. The competitive Inhibitor has a similar shape to substrate; 3. which binds to the active site 4. this Inhibition can be overcome by more substrate
2. non-comp Inhibitor binds to site on enzyme other than
   active site; 6. which changes the shape of the active site;
3. Cannot be overcome by adding more
   substrate;
