Understanding Metabolism

What is the primary function of metabolism in the human body?

• To increase body weight

• To decrease body temperature

• To facilitate chemical reactions that sustain life

• To store energy for future use

Which of the following is true about Basal Metabolic Rate (BMR)?

• It only occurs during sleep

• It is higher than Total Metabolic Rate (TMR)

• It is the energy used for basic life functions

• It includes all physical activities

Why do children generally have a higher metabolism compared to adults?

• They eat more frequently

• They require more energy for growth

• They have more muscle mass

• They sleep longer hours

How does the body’s energy demand affect metabolism?

• Energy demand has no impact on metabolism

• Higher energy demand slows down metabolism

• Metabolism remains constant regardless of energy demand

• Metabolism speeds up with increased energy demand

What was the surprising finding about muscle gains and BMR?

• Increased muscle mass significantly raises BMR

• Muscle gains only affect TMR, not BMR

• Muscle gains have no effect on BMR

• BMR decreases with more muscle mass
