Questions: Raise the activation energy Question 4 1 pts A nonprotein organic molecule required by an enzyme for complete enzyme function. Many are made from vitamins Cofactor Apoenzyme Coenzyme Mineral Exoenzyme Question 5 3 pts

The answer is the third one (Coenzyme): A nonprotein organic molecule required by an enzyme for complete enzyme function. Many are made from vitamins.

Explanation for each option:

• Cofactor: This is a general term for a non-protein chemical compound or metallic ion that is required for an enzyme's activity as a catalyst. Cofactors can be either inorganic (such as metal ions) or organic molecules. Coenzymes are a subset of cofactors.

• Apoenzyme: This refers to the protein portion of an enzyme, which requires a cofactor to become an active enzyme (holoenzyme). It is not a nonprotein organic molecule.

• Coenzyme: This is the correct answer. Coenzymes are organic molecules that bind to the enzyme and are necessary for its activity. They are often derived from vitamins.

• Mineral: Minerals are inorganic elements that can act as cofactors but are not organic molecules.

• Exoenzyme: This term refers to enzymes that are secreted by a cell and function outside of that cell. It is not related to the requirement of a nonprotein organic molecule for enzyme function.

In summary, the correct answer is Coenzyme, as it fits the description of a nonprotein organic molecule required by an enzyme for complete function and is often derived from vitamins.
