a) Coenzymes; Inorganic cofactors; Active enzymes
b) Cofactors; Inactive enzymes; Active enzymes
c) Inorganic cofactors; Active enzymes; Inactive enzymes
d) Active enzymes; Inactive enzymes; Coenzymes

Answer 1

Apoenzyme, cofactors, and coenzymes are all important components in enzyme function. Apoenzymes require cofactors or coenzymes to be active, and when they bind together, they form a holoenzyme which is the active form of the enzyme.

Step-by-step explanation:

Apoenzyme, cofactors, and coenzymes play crucial roles in enzyme function. Apoenzymes are enzymes that require a non-protein portion called a cofactor to be active. Cofactors can be inorganic ions or organic compounds, with the organic compounds known as coenzymes. When an apoenzyme binds to a cofactor or coenzyme, it forms a holoenzyme which is the active form of the enzyme. For example, coenzyme A (CoA) is a commonly used coenzyme that binds to the enzyme's active site, aiding in the transition of a substrate to a product. Without CoA, the enzyme would be inactive as an apoenzyme.
