Aerobic respiration converts glucose and oxygen into ATP, CO₂, and water in mitochondria. It provides essential energy for cellular functions. Aerobic respiration is a set of metabolic reactions that take place in the presence of oxygen, occurring in a cell to convert chemical energy into ATPs. Anaerobic respiration is a process of cellular respiration where the high energy electron acceptor is neither oxygen nor pyruvate derivatives. Learn what aerobic respiration is, how it differs from anaerobic respiration , and which organisms use it. Explore the four steps of aerobic respiration with diagrams and chemical equations. The aerobic respiration diagram given below represents the entire process of aerobic respiration . The different cycles involved in aerobic respiration such as glycolysis, Krebs cycle, electron transport chain are clearly mentioned in the diagram.
