Question

1. what are the two main types of cofactors? 8. what would be +be

require to become a holoenzyme?

Explanation:

Question 7: Cofactors are non-protein molecules that assist enzymes. They are grouped into two main classes based on their chemical nature and binding strength.
Question 8: A holoenzyme is the fully functional form of an enzyme, which requires the combination of the enzyme's protein part and a cofactor.

Answer:

1. The two main types of cofactors are:

• Inorganic ions (e.g., zinc, magnesium ions)
• Coenzymes (organic molecules, e.g., NAD⁺, FAD, many are vitamins or derived from vitamins)

1. An apoenzyme (the inactive protein portion of an enzyme) must bind to a cofactor (either an inorganic ion or a coenzyme) to become a holoenzyme.
