WebJul 4, 2024 · In glycolysis and gluconeogenesis seven of the ten steps occur at or near equilibrium. In gluconeogenesis the conversion of pyruvate to PEP, the conversion of fructose-1,6-bP, and the conversion of glucose-6-P to glucose all occur very spontaneously which is why these processes are highly regulated. WebSome books state 36 ATP per glucose but this occurs in cells that convert the 2 NADHs made in glycolysis into 2 FADH2s when they enter the mitochondria where Krebs cycle and ETC occur. (It is a transporter phenomenon and has nothing to do with using ATP.) If you do the math, you end up with 2 less ATP. This approach has worked well for over 30 ...

WebMar 23, 2024 · The products of glycolysis from one molecule of glucose are: 2 x ATP 2 x NADH 2 x pyruvate Pyruvate is an essential component of the citric acid cycle. This pyruvate is broken down to produce acetyl-CoA, the central molecule of the Krebs cycle. Glycolysis is, therefore, the method by which a cell can manufacture enough acetyl CoA to produce … WebThe overall energy cost of the oxidative pentose phosphate pathway is 0 ATP and 2 NADPH. Tricarboxylic Acid Cycle (TCA Cycle): The TCA cycle, also known as the Krebs cycle, converts acetyl-CoA into CO2 and generates energy in the form of NADH and FADH2. The net energy yield of the TCA cycle is 2 ATP, 6 NADH, and 2 FADH2. WebGlycolysis occurs in the cytosol of cells. Once finished, the two pyruvate products are transported into the mitochondria to go through the citric acid cycle, at a cost of 1 ATP per pyruvate. Neither the nucleus, nor the endoplasmic reticulum have any function in glycolysis or the citric acid cycle. Report an Error flysoft inc liberty mo
