Cellular Respiration: How Do Cells Get Energy?

Cellular respiration is the process through which the cell generates energy, in the form of ATP, using food and oxygen. The is a multistep biochemical process where food, primarily the carbohydrate glucose, is broken down to produce energy.

There are three steps in cellular respiration:
Glycolysis
The Krebs cycle
Electron Transport Chain and Oxidative phosphorylation
