Chapter 8 & 9 - Enzymes and Respiration

Question 1

Cofactors

Answer 1

inorganic ions, such as Zn2+, Mg2+, and Fe2+, that reversibly interact with enzymes
(organisms require these minerals in their diet)

Question 2

Coenzymes

Answer 2

organic molecules, such as NADH or FADH2, that interact with enzymes
(Some of these are required in the diet and are called vitamins. Some vitamins are precursors to coenzymes)
