What term signifies a positive nitrogen balance during periods of growth and recovery?

1. Catabolism

2. Anabolism

3. Hypermetabolism

4. Hypometabolism

The correct answer is: Anabolism

The term that signifies a positive nitrogen balance during periods of growth and recovery is anabolism. Anabolism refers to the metabolic processes that construct molecules from smaller units, which is crucial during periods of growth, such as childhood, adolescence, and recovery from illness or injury. During these times, the body needs to build new tissues—such as muscle and other proteins—leading to an increased retention of nitrogen, which is a key component of amino acids and proteins. When the body is in a state of anabolism, it effectively takes in more nitrogen (through protein synthesis) than it excretes (through urine and other means), resulting in a positive nitrogen balance. This state is essential for healthy growth and healing processes, as it supports muscle development, tissue repair, and overall growth. In contrast, catabolism involves the breakdown of molecules, typically releasing energy and leading to a negative nitrogen balance. Hypermetabolism refers to an increased metabolic rate, often associated with stress or illness, and can lead to a catabolic state if not balanced with adequate nutrition. Hypometabolism denotes a reduced metabolic rate, which is not conducive to growth or recovery. Understanding these metabolic states is crucial for health coaches aiming to support clients through various life stages and health challenges.
