Enzyme inhabitation and activation

Question 1

what are enzymes inhibitors

Answer 1

Affect the binding of other molecules

Question 2

what are the two categories of enzyme inhibitors

Answer 2

• competitive inhibitor

- non-competitive inhibitor

Question 3

what is a competitive inhibitor

Answer 3

A competitive inhibitor will bind to an enzyme at the active site. This blocks the substrate from binding, preventing the enzyme from catalysing the reaction.

Question 4

what is a non-competitive inhibitor

Answer 4

A non-compeptive inhibitor will bind to an enzyme somewhere other than the active site. This binding causes a change to the shape of the enzyme’s active site.

Question 5

what are enzyme activators

Answer 5

They activate enzymes by binding

Question 6

what are the two categories of activators

Answer 6

• coenzymes

- cofactors

Question 7

what are cofactors

Answer 7

Are small inorganic substances, often metal ions

Question 8

what are coenzymes

Answer 8

Are small non-protein organic substances such as vitamins

Question 9

what is enzyme activation

Answer 9

It can be caused by the change of conformation in the enzyme or by providing the active site

Question 10

what is an example of enzyme activators

Answer 10

Vitamin B1 is converted into a coenzyme that is involved in the breakdown of glucose
