- They are used in the biosynthesis of other molecules or… - They are stored for future energy needs such as fat. Energy - Energy is needed even when the body is at rest. - This is called basal metabolic rate or BMR. - BMR is measure when the body is at rest, has not eaten in 12 hours and has not engaged in vigorous activity for several hours. - BMR is affected by many things such as disease, weight, diet. - BMR declines after early adulthood by 2 to 3% per decade. - BMR increases immediately with voluntary activity. A lot of medicine that is given to children, has never been tested in children. Sooo…they take the adult dosage and divide by the respective body weight.
