Answer to Question 1

A
Feedback:
The actual amount of energy expended on physical activity depends on the intensity and duration of the activity and the weight of the person performing the activity. The more intense and longer the activity, the greater is the amount of calories burned.

Answer to Question 2

B
During recovery from a serious accident, the physical stress and immobility cause loss of muscle tissue through catabolism. Anabolism occurs when new protein is being formed during growth or healing. Deamination is one part of catabolism; it refers to removal of the amino group when amino acids are broken down. Metabolism is a general term that includes both anabolism and catabolism.
