Voit demonstrated that oxygen consumption is the result of cellular metabolism, while Rubner measured the major energy value of certain foods in order to calculate the caloric values that are...
The human body carries out its main functions by consuming food and turning it into usable energy. Immediate energy is supplied to the body in the form of adenosine triphosphate (ATP). Since ATP is the primary source of energy for every body function, other stored energy is used to replenish ATP.
The rate at which the body uses food energy to sustain life and to do different activities is called the metabolic rate. The total energy conversion rate of a person at rest is called the basal metabolic rate (BMR) and is divided among various systems in the body, as shown the following table:
30 Νοε 2016 · Energy expenditure in humans is determined by body size and body composition, environment and behavior. A larger body, especially a larger fat-free mass, requires more maintenance and...
