Answer 1

QUESTION 13-

ANSWER- all of the above may affect metabolic rate.

EXPLANATION -

Metabolic rate -

• definition - minimum amount of energy required by the body to maintain life at complete physical and mental rest in the post - absorptive state.

Factors that affect metabolic rate -

• Age - infants and growing children have higher metabolic rate. Metabolic rate decrease with age.
• Gender - men have higher metabolic rate than female.
• Lean muscle mass - metabolic rate increases with increase in lean muscle mass.
• Harmones- thyroid harmone increase metabolic rate.
• Starvation/Fasting - metabolic rate decrease during starvation. So diet also have affect on metabolic rate.
• Physical Activity - metabolic rate increases with regular physical exercise.
• Environment- metabolic rate is higher in cold climate compare to warm conditions.
• Fever - metabolic rate increases with fever.
• Disease - metabolic rate in infection, leukemia, cardiac failure, hypertension increases.
• Pregnant women have more metabolic rate.
• A taller thin person have more metabolic rate than a shorter fatter person.

So all the above given factors affect metabolic rate.
