All About Cellular Respiration

The energy that powers our cells is obtained from the foods we eat. The most efficient way for cells to harvest energy stored in food is through cellular respiration.

Glucose, derived from food, is broken down during cellular respiration to provide energy in the form of ATP and heat. Cellular respiration has three main stages:

• Glycolysis
• The citric acid cycle
• Electron transport
