Question

What happens to heat energy that is released during cellular respiration?

Answer 1

Only 30-40 % of energy is used from glucose to make ATP. Most (60-70%) is lost as heat. Once the heat reaches the skin in humans, it can be transferred to the external environment in one of four ways: conduction and convection (20% total), evaporation (20%), and radiation (60%).

Answer 2

The energy is transferred as heat into the environment. The cell then is able maintain a constant temperature for optimum growth.
