Enzyme inhibition

Question 1

Competitive inhibitor

Answer 1

Have similar shape to substrate molecules. Compete with substrate to bind to active sites block the active site so substrate cannot bind. No enzyme substrate complex is formed.

Question 2

Non-competitive inhabitation

Answer 2

Do not bind to active sites have different shape to substrate, so do not compete. Find to a site away from active site known as the allosteric site. Causes active site of the enzyme to change shape, so it is no longer complimentary to subject so no enzyme complexes can be formed.
