Question

Quizplus · Accepted Answer

Positive nitrogen balance means that the body is retaining more nitrogen than it excretes, indicating that the body is building and retaining protein. This occurs during periods of growth, such as infancy, childhood, and adolescence, when the body is adding new tissue. During old age, the body tends to have a negative nitrogen balance, meaning that more nitrogen is excreted than retained, due to decreased protein synthesis and increased protein breakdown. Exercise and infections can also increase nitrogen balance temporarily, but the most consistent answer is A for growth.
