Question 22

What is substrate?

Answer 22

A substance that lies beneath another substance, the reactant reactions catalyzed by enzymes

Question 23

What is chemical equilibrium?

Answer 23

A state of balance in which rate of a forward reaction equals the rate of the reverse reaction and the reactant stay the same
