Answer to Question 2
ANS: 1, 2, 4, 6
Proteins provide a source of energy (4 kcal/g), and they are essential for synthesis (building) of body tissue in growth, maintenance, and repair. Collagen, hormones, enzymes, immune cells, DNA, and RNA are all made of protein. In addition, blood clotting, fluid regulation, and ac-id-base balance require proteins. These proteins transport nutrients and many drugs in the blood. There is not a direct connection between the other options and protein.
