Coenzymes, Cofactors + Prosthetic Groups

Question 1

What are co-factors?

Answer 1

-some enzymes need a small non-protein molecule to attach to them to catalyse reactions
-require inorganic ions to function
-may help stabilise

Question 2

What are coenzymes?

Answer 2

-larger organic cofactors
-temporarily binds to enzyme active site
-eg. Vitamins

Question 3

What are prosthetic groups?

Answer 3

-cofactors permanently bonded to an enzyme
-essential to function to help form final 3D shape

Question 4

What are co-substrates?

Answer 4

-cofactors that works with substrate to form correct shape
