Begin by understanding the process of aerobic cellular respiration, which consists of several stages: Glycolysis, Krebs Cycle (Citric Acid Cycle), and Electron Transport Chain.
Glycolysis is the first step, occurring in the cytoplasm, where glucose is broken down into pyruvate, producing ATP and NADH.
The Krebs Cycle takes place in the mitochondria, where pyruvate is further broken down, releasing carbon dioxide and generating more ATP, NADH, and FADH2.
The Electron Transport Chain is the final step of aerobic respiration, located in the inner mitochondrial membrane. Here, electrons from NADH and FADH2 are transferred through protein complexes, creating a proton gradient that drives ATP synthesis.
Recognize that the Electron Transport Chain is the last step in aerobic cellular respiration, where the majority of ATP is produced through oxidative phosphorylation.
