Which process supplies energy for keeping the body warm?

Cellular respiration is the process that supplies energy for keeping the body warm. It is a set of metabolic reactions that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. This process is essential for the survival of all living organisms because ATP serves as the main energy currency for cells.

The overall chemical equation for cellular respiration is:

C₆H₁₂O₆ (glucose) + 6O₂ (oxygen) -> 6CO₂ (carbon dioxide) + 6H₂O (water) + energy (as ATP)

During cellular respiration, glucose, which is a type of sugar obtained from food, is broken down in the presence of oxygen to produce carbon dioxide, water, and energy. The energy released from the breakdown of glucose is stored in the form of ATP molecules, which can be used to power various cellular processes, including maintaining body temperature.
