C
Thiamine needs are related to metabolic rate (i.e., energy expenditure) because thiamine is a coenzyme in energy metabolism. Thiamine is not directly involved in protein metabolism. The vitamin where requirements are inversely related to skin exposure to sunlight is vitamin D. Phy-siologic and emotional stress do not affect thiamine needs.
