有氧呼吸过程中ATP产量最大值旁边的新文章 新文章:有氧呼吸过程中最大ATP产量

这张表显示了有氧细胞呼吸过程中ATP产量的最大值:

表显示有氧呼吸过程中ATP的最大产量。该表显示了在有氧呼吸过程中产生38种潜在ATP的时间。色谱柱在呼吸、碳流、底物水平磷酸化、氧化磷酸化和ATP最大产量的步骤中进行标记。第一步:糖酵解。碳流:葡萄糖，6个碳，生成2个丙酮酸，每个3个碳。从底物水平磷酸化:2 ATP产生。从氧化磷酸化:6 ATP产生的2 NADH。糖酵解的最大ATP产量:8个ATP。下一步:过渡反应。碳流:2个丙酮酸，每个3个碳，变成2个碳的乙酰基。 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.
