Verified step by step guidance1
Begin by understanding the stages of glucose metabolism: Glycolysis, Citric Acid Cycle, and Electron Transport Chain (ETC) + Oxidative Phosphorylation.
Glycolysis occurs in the cytoplasm and breaks down glucose into pyruvate, producing a small amount of ATP.
The Citric Acid Cycle, also known as the Krebs Cycle, takes place in the mitochondria and generates electron carriers (NADH and FADH2) but only a small amount of ATP directly.
The Electron Transport Chain (ETC) is located in the inner mitochondrial membrane, where electrons from NADH and FADH2 are transferred through protein complexes.
Oxidative Phosphorylation is the process where the energy from electrons in the ETC is used to pump protons across the membrane, creating a gradient that drives ATP synthesis, producing the majority of ATP in glucose metabolism.
