What is aerobic respiration?

Explanation:
Aerobic respiration is cellular respiration that requires oxygen and yields more ATP per glucose. When oxygen is present, glucose is fully oxidized through glycolysis, the citric acid cycle, and the electron transport chain in mitochondria, with oxygen acting as the final electron acceptor to form water. This chain pumps protons to generate a large amount of ATP, typically about 30–32 per glucose, while releasing carbon dioxide and water as byproducts. If oxygen isn’t available, cells rely on less efficient pathways that produce far less ATP. This process is distinct from photosynthesis, which uses light to build sugars, and from simply breaking down ATP to ADP, which releases energy without harvesting it from glucose.
