What is the rate at which energy is needed for body maintenance?

• A. Basal metabolism rate
• B. Avitaminosis
• C. Bioavailable
• D. Atherosclerosis

Answer: (A)

Basal metabolic rate is the rate at which energy is needed for body maintenance. It represents the energy the body uses at rest to sustain essential functions such as breathing, circulating blood, maintaining organ activity, and cellular processes. This rate is measured under strict conditions (no recent meals, at rest, in a comfortable temperature) and forms the baseline of daily energy expenditure. The other terms listed don’t describe energy needs: avitaminosis is vitamin deficiency, bioavailable refers to how much of a nutrient can be absorbed and used, and atherosclerosis is the buildup of plaque in arteries.
