Because it is the actual amount of calories expended. NEE = GEE (Gross Energy Expenditure) - REE (Resting Energy Expenditure). Source: My B.S. in Exercise Science/Kinesiology
A person's energy requirement is the amount of energy he or she needs to maintain health, growth, and a level of activity. A person's energy expenditure is the amount of energy he or she uses, and the measure of this can be used to determine the person's energy requirements. Energy expenditure can be calculated either with an equation or by direct measurement.
Osmosis is the membrane activity that does not require the expenditure of energy by the cell. It does not require any input of energy.
Energy expenditure is that amount of calories that someone uses in one day by exercising or doing everyday tasks.
55 - 75% of daily energy expenditure
The potential energy increases because of the weightlifter lifting it above his head (Hope this helps)XP
Energy expenditure is measured a couple of ways. It's measured by a person's basal metabolism, maximal oxygen consumption, and BMR.
Recycling does not create energy. It reduces the expenditure of energy.
Energy intake < energy expenditure = weight loss.
Age Gender Activity level note: weight is also a factor in energy expenditure
active transport reguire energy.
The directed expenditure of energy.
Never during a marathon. Your body does not have the ability to metabolize fats into energy during the time it takes to run a marathon.
