WebAug 13, 2024 · The Krebs Cycle is also known as the citric acid cycle or the tricarboxylic acid cycle (TCA cycle). Within the mitochondria, each pyruvate is broken apart and combined with a coenzyme known as CoA to form a 2-carbon molecule, acetyl-CoA, which can enter the Krebs Cycle. A single atom of carbon (per pyruvate) is "lost" as carbon dioxide. WebExpert Answer. 100% (10 ratings) Total of 2 NADH mol. are produced during conversion of Pyruva …. View the full answer.

WebThe commonly accepted number is 4 H+ per 1 ATP (though this is still an area of research). Thus, since NADH contributes to pumping 10 H+, the equation is (10 H+ pumped)/ (4 H+ needed) = 2.5. Similarly, for FADH2, it is (6 H+ pumped)/ (4 H+ needed) = 1.5. They aren't actually making half ATPs; it's just an approximation based on how many H+ they ...
