Aerobic Respiration Powers Cells with Oxygen and Glucose

Source: savemyexams.com

Aerobic respiration is the process where cells use oxygen to break down glucose for energy.
It produces 38 ATP molecules per glucose, carbon dioxide, and water as waste.
This powers all body activities, from muscle movement to keeping cells alive.

Aerobic respiration happens in human cells' mitochondria using oxygen to fully convert glucose into energy. The revision notes explain the chemical equation, stages like glycolysis and the Krebs cycle, and how it links to the respiratory system. It matters because this process fuels daily life and shows why we breathe - to supply oxygen for energy production.
