A
instant energy for the cell/body
B
hormones, buoyancy, forms cell membranes, insulation, energy storage
C

Explanation: 

Detailed explanation-1: -Protein has many roles in your body. It helps repair and build your body’s tissues, allows metabolic reactions to take place and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance.

Detailed explanation-2: -Dietary protein is required to promote growth, repair damaged cells and tissue, synthesize hormones, and for a variety of metabolic activities.

Detailed explanation-3: -These proteins provide structure and support for cells. On a larger scale, they also allow the body to move. These proteins bind and carry atoms and small molecules within cells and throughout the body.

Detailed explanation-4: -While the primary role of protein is to repair damaged tissues, it can also be used to produce energy for muscle contractions when other sources of adenosine triphosphate (ATP, the cellular form of energy), namely fats and carbohydrates, are not available.

Detailed explanation-5: -Protein is a nutrient used to make and repair our body cells (like blood and muscle cells).
