The correct answer is B.Long term energy.

Explanation:

Proteins serve many important functions in the body, but long-term energy storage is not one of them. That role is primarily carried out by lipids (fats) and carbohydrates.

Here’s a breakdown of the functions of proteins:

A.Catalysts: Proteins act as enzymes, which are biological catalysts that speed up chemical reactions in the body.

C.Transport: Proteins are involved in transporting molecules. For example, hemoglobin is a protein that transports oxygen in the blood, and membrane proteins help move substances across cell membranes.
