enzymes

Explanation:

Proteins are essential macromolecules in the body. Muscle tissue is made up of proteins like actin and myosin. While carbohydrates are the primary energy source, proteins can be broken down for energy in certain situations. Antibodies (a type of protein) are crucial for the immune response. Enzymes (which are proteins) catalyze biochemical reactions. However, insulating the body is mainly a function of fats (adipose tissue), not proteins.

Answer:

Muscle tissue, Energy, Immune response, Enzymes.
