Cellular Respiration

Cellular respiration is a process that breaks down food molecules to capture energy in ATP. It involves three main stages: glycolysis, the Krebs cycle, and the electron transport chain with ATP synthase. Glycolysis occurs in the cytoplasm, splitting glucose into pyruvic acid and producing ATP and NADH. The Krebs cycle, in the mitochondria, further breaks down pyruvic acid, generating more ATP, NADH, and FADH. The electron transport chain uses these molecules to produce a large amount of ATP, completing the energy conversion process.
