What is the approximate percentage efficiency of conversion of food energy to ATP energy in the body?

The body converts the chemical energy of food to the chemical energy of ATP with about 50 percent efficiency, radiating the rest as heat.


What is the energy in a human body?

Energy is stored as chemical energy in human body. It is consumed when required.


What is the percent efficiency of conversion of food energy to ATP energy in the body?

(# of ATP produced X Energy needed to produce ATP)---- Complete Oxidation of Glucose


What is the specific heat capacity of human body?

With regard to work output vs. caloric input, the thermodynamic efficiency of a human being is about 25%. This comes from measuring the work output of cyclists compared to the oxygen they consume. However, some of the energy value of the food people eat exits the body unused, because it is not metabolized. The unused portion might be 1/3 to 1/2 of the total energy value ingested. When the unused food energy value is included, the thermodynamic efficiency thus drops to 13% to 17%.


The most efficient energy source for the body comes from?

Why is it more energy efficient for humans to eat corn than beef?

Do you mean more energy efficient for the human's digestive system or more energy efficient for business' and corporations to produce? For a human, eating meat will be more energy efficient. This is because Meat will contain more fats which means more energy. Grains and vegetables are full of crap which the human body cannot fully digest. This means we have to cook or process the hell out of to absorb more of the nutrients plus eat a whole lot more because its less energy dense than the meat. Corporations try to promote grains as much as possible because they are easy to produce on a mass scale for maximum profit. THAT IS ALL THEY WANT, MAXIMUM PROFIT. They can have fields and fields crammed with corn or wheat making it more space efficient (Try cram hundreds of cows together and you get disease and there is not enough grass on the ground for them to eat so they feed them with....corn - cows aren't designed for this!) In terms of energy efficiency meat production and processing requires more hands on work from people where grains can be all processed more buy machines alone.
