Question 1:

What is basal metabolic rate (BMR)?

A) The rate at which you burn calories during physical activity
B) The rate at which your body burns calories at rest to maintain basic functions
C) The rate at which you metabolize carbohydrates
D) The rate at which your body absorbs nutrients from food

Show Answer

Explanation: Basal metabolic rate (BMR) is the rate at which your body burns calories at rest to maintain basic functions such as breathing, circulating blood, and regulating body temperature.

Question 2:

Which of the following factors can influence basal metabolic rate (BMR)?

A) Age and gender
B) Body composition and muscle mass
C) Hormonal levels
D) All of the above

Show Answer

Explanation: All of the above factors can influence basal metabolic rate (BMR). Age, gender, body composition, muscle mass, and hormonal levels can impact the rate at which the body burnscalories at rest.

Question 3:

Which of the following statements about muscle mass and metabolism is true?

A) Increasing muscle mass decreases basal metabolic rate (BMR)
B) Muscle tissue burns more calories at rest compared to fat tissue
C) Muscle tissue has no impact on metabolism
D) Muscle mass only affects metabolism during exercise

Show Answer

Explanation: The statement that is true is that muscle tissue burns more calories at rest compared to fat tissue. This is because muscle is a metabolically active tissue that requires more energy for maintenance, contributing to a higher basal metabolic rate (BMR).

Question 4:

How does age affect basal metabolic rate (BMR)?

A) BMR increases with age
B) BMR decreases with age
C) Age has no impact on BMR
D) BMR remains constant throughout life

Show Answer

Explanation: The correct answer is that BMR decreases with age. This is because as we age, there tends to be a gradual loss of muscle mass and a decrease in physical activity, both of which contribute to a lower metabolic rate.

Question 5:

How can hormone levels influence basal metabolic rate (BMR)?

A) Hormones have no impact on BMR
B) Higher levels of certain hormones increase BMR
C) Lower levels of certain hormones increase BMR
D) Hormone levels have a direct correlation with body weight

Show Answer

Explanation: Higher levels of certain hormones can increasebasal metabolic rate (BMR). Hormones such as thyroid hormones and catecholamines, like adrenaline, can stimulate metabolic activity and increase energy expenditure, leading to a higher BMR.
