MULTIPLE CHOICE
| a. | the body would manufacture amino acids to make essential proteins from fatty acids and glycogen. |
| b. | body metabolism would decrease to conserve amino acids until protein intake was resumed. |
| c. | the liver would recirculate amino acids instead of breaking them down and excreting urea. |
| d. | the body would break down muscle tissue to provide amino acids to make essential proteins. |
ANS: D
The body needs regular dietary protein to provide amino acids. If no protein is eaten in the diet, the body uses muscle tissue to provide amino acids to make essential body proteins. The liver cannot recirculate amino acids; some are always broken down, and the nitrogen portion is excreted as urea. Body metabolism may decrease slightly, but it would not be sufficient to conserve amino acids for any length of time. The body cannot manufacture amino acids from fatty acids and glycogen.

| a. | less than 100% |
| b. | between 100% and 150% |
| c. | between 150% and 200% |
| d. | greater than 200% |
ANS: D
The RDA for protein is 0.8 g per kilogram of body weight. This man’s weight is 190 lb, or 86 kg; 86 kg ´ 0.8 = 69.1 g protein per day. Thus, an intake of 150 g is more than twice his RDA of 69.1 g of protein per day.

| a. | primary |
| b. | secondary |
| c. | tertiary |
| d. | quaternary |
ANS: B
The alpha helix structure is an example of the secondary structure of proteins. The primary structure is the amino acid sequence. The tertiary structure comprises bonds that form within chains in loops or folds. Quaternary structure is formed by combinations of more than one polypeptide.

| a. | most amino acids contain sulfur. |
| b. | they are stored in the liver for use when needed. |
| c. | essential amino acids cannot be manufactured by body cells. |
| d. | nonessential amino acids cannot be manufactured body cells. |
ANS: C
Body cells cannot manufacture essential amino acids. Cells can make nonessential amino acids from essential amino acids. The liver is not able to store significant amounts of amino acids. Some but not most amino acids contain sulfur.
