Question

multiple select question
select all that apply
choose all that may contribute to negative nitrogen balance.

muscle atrophy
childhood
insufficient carbohydrate and fat intake
pregnancy
stress

Explanation:

• Muscle atrophy: Involves muscle breakdown, increasing protein (nitrogen - containing) breakdown, leading to negative nitrogen balance.
• Insufficient carbohydrate and fat intake: Forces the body to use protein for energy, increasing protein catabolism and negative nitrogen balance.
• Stress: Can increase metabolic rate and protein breakdown, contributing to negative nitrogen balance.
• Childhood and pregnancy are periods of growth, requiring positive nitrogen balance (more nitrogen intake than loss) as the body is building tissues.

Answer:

A. Muscle atrophy, C. Insufficient carbohydrate and fat intake, E. Stress
