CELLULAR RESPIRATION: Energy Conversion in the Body

Last Updated: March 20, 2019

Cellular Respiration

The single-most important biochemical reaction human beings need is cellular respiration. Without it, we wouldn’t exist.

Our cells require oxygen to break down the food we consume. From glucose and oxygen, cellular respiration is the mechanism that gives us the energy we need to live.

All the chemical reactions in living things run off ATP. Basically, sugars, fats and proteins turn into ATP which is the usable form of energy for biological systems like ours.
