Question 1

Enzyme inhibitors

Answer 1

An inhibitor is a molecule that prevents enzymes from carrying out their normal function of catalysis

Question 2

Competitive inhibitors

Answer 2

Molecules/part of a molecule that has a similar shape to the subpage of an enzyme can fit into the enzymes active site. This enzyme is no longer able to carry out its function. In a solution with these molecules, substrates and enzymes, the substrate and molecule will compete to bind to the active site of the enzymes, slowing down the rate of reaction

Question 3

Non-competitive inhibitors

Answer 3

The inhibitor binds to the enzyme in a location other than the active site. This binding changed the tertiary structure of the enzyme and therefore changes the shape of the active site. This means that the complementary substrate will no longer be able to bind to the enzyme and so the enzyme cannot carry out its function.

Question 4

Coenzyme

Answer 4

Organic molecule that binds to an active site of a molecule to assist in the catalysis of its function. They could also transfer

Question 5

Cofactors

Answer 5

Inorganic coenzyme
