enzymes (Inhibitors)

Question 1

Functions

Answer 1

Regulate metabolic processes Medicinal drugs Metabolic poisons

Question 2

Types

Answer 2

Non-reversible inhibitors Reversible inhibitors: Competitive Non-competitive

Question 3

Non-reversible

Answer 3

They bond covalently with enzymes to block or change the shape of the active site. This example: Medicinal drug: Aspirin Metabolic poison: Cyanide

Question 4

Reversible inhibitors: Competitive

Answer 4

They compete with the substrate to bind with the active site of an enzyme, by doing this they block the enzyme’s active site so it is unable to do its function

Example:

Statin: Inhibits enzymes used in synthesis of cholsterol.

Question 5

Reversible inhibitors: Non-competative

Answer 5

The inhibtor binds to the allosteric site of the enzyme, this causes the active site of the enzyme to change shape, causing it to become non complementary. As of thsi the substrate can no longer bid to te active site so the enzymes function can no longer be carried out.
