This table shows the maximum ATP yield during aerobic cellular respiration:

一个表显示在ae ATP的最高产量robic respiration. The table indicates when each of the 38 potential ATP are produced during aerobic respiration. The columns are labelled step in respiration, carbon flow, substrate-level phosphorylation, oxidative phosphorylation, and ATP maximum yield. First step: glycolysis. Carbon flow: Glucose, 6 carbon, to 2 pyruvates, 3 carbon each. From substrate level phosphorylation: 2 ATP produced. From oxidative phosphorylation: 6 ATP produced from 2 NADH. Maximum ATP yield from glycolysis: 8 ATP. Next step: transition reaction. Carbon flow: 2 pyruvate, 3 carbon each, to 2 acetyl of 2 carbon each. 2 carbon released as carbon dioxide. From substrate-level phosphorylation: no ATP produced. From oxidative phosphorylation: 6 ATP produced from 2 NADH. Maximum ATP yield from transition reaction: 6 ATP. Next step: Krebs cycle. Carbon flow: 2 acetyl of 2 carbon each, to 4 carbon dioxide molecules. From substrate-level phosphorylation: 2 ATP produced. From oxidative phosphorylation: 18 ATP from 6 NADH plus 4 ATP from 2 FADH2. Maximum ATP yield from Krebs cycle: 24 ATP. Final row: total summary. Carbon flow: 6 glucose to 6 carbon dioxide. From substrate level phosphorylation, 4 ATP produced. From oxidative phosphorylation: 34 ATP produced from 12 NADH and 2 FADH2. Maximum total ATP yield: 38 ATP.
