Module 5—Photosynthesis and Cellular Respiration

Reflect and Connect

 

The purpose of aerobic respiration is to provide organisms with energy to complete voluntary and involuntary tasks. This energy ultimately comes from glucose created in photosynthesis. Glucose can become a part of other molecules like fats and proteins, but before those molecules hit the Krebs cycle they have been catabolized. ATP synthesized in the electron transport chain is available to cells. Cells can then perform functions that help people move about (muscle contractions) and keep them alive (nerve transmission). Energy is derived from the organic compound glucose.
