Which of the following statements is FALSE regarding the effects of exercise on metabolism and body composition? Group of answer choices It slightly raises the metabolic rate for several hours after exercise. The increase in muscle mass raises the metabolic rate. It increases caloric expenditure and thus helps regulate body weight. It can result in substantial weight gain due to increase in muscle mass.

The false statement regarding the effect of exercise on metabolism and body composition is that (It can result in substantial weight gain due to increase in muscle mass).

Explanation:

Metabolism of the body simply means all the chemical reactions in all the cells of the body and the metabolic rate is normally expressed in terms of the rate of heat liberation during chemical reactions or physical activities.

The body composition of healthy adults who maintain stable body weight, energy intake is balanced with energy output. Energy output includes energy used for:

--> performing essential metabolic functions of the body.

--> performing various physical activities (exercise)

--> digesting, absorbing and processing food.

--> maintaining body temperature.

When an individual performs exercise, the rate at which heat is liberated( metabolic rate) is increased. This is because ATP which is gotten from the food is used as energy during exercise and is converted to heat as the end product.

Also, increase in muscle mass raises the metabolic rate because the more muscle in the body, the more calories are used up during rest and therefore the higher your metabolic rate.

Therefore the statement is false about the effects of exercise on metabolism and body composition because exercise involves energy output cannot lead to SUBSTANTIAL weight gain even in increased muscle mass.

enzyme speed up the reactions

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.
