Q: Which of the following is NOT a function of proteins?
Solution: While proteins can be involved in energy metabolism, they are not primarily used for energy storage; carbohydrates and fats serve that purpose.
Steps: 5
Step 1: Understand what proteins are. Proteins are large molecules made up of amino acids and play many roles in the body.
Step 2: Identify the functions of proteins. Proteins help build and repair tissues, act as enzymes, transport molecules, and support immune function.
Step 3: Recognize that proteins can be used for energy, but this is not their main role. The body prefers to use carbohydrates and fats for energy.
Step 4: Determine what energy storage means. Energy storage refers to how the body keeps energy for later use, primarily through carbohydrates (like glycogen) and fats (like adipose tissue).
Step 5: Conclude that since carbohydrates and fats are the main energy storage molecules, the statement that proteins are not primarily used for energy storage is correct.
