When our bodies extract energy from food and convert it to a form that our cells can use, how much total food energy is lost as heat? a. 75 percent b. less than 10 percent c. more than 50 percent d. 20 percent

Option C

Explanation: The food that is eaten is used in ATP production and rest of it is released in the form of heat. The food that is eaten undergoes the process of cellular respiration.

This process of cellular respiration helps in the breakdown of the glucose into ATP. An average cell uses 40% of the energy for conversion into adenosine triphosphate and approximately 60% of the energy is released in the form of heat.

So, more than 50% of the food energy is lost in the form of heat.
