immune response

Explanation:

• Energy: Proteins can be broken down to provide energy, especially when carbohydrate and fat stores are low.
• Enzymes: Most enzymes are proteins. Enzymes catalyze biochemical reactions in the body.
• Muscle tissue: Actin and myosin are proteins that make up muscle fibers, enabling muscle contraction and movement.
• Immune response: Antibodies (immunoglobulins) are proteins that play a crucial role in the immune system by recognizing and neutralizing pathogens.
• Insulate the body: This is primarily a function of fats (adipose tissue), not proteins.

Answer:

Energy, Enzymes, Muscle tissue, Immune response.
