Hoeveel ATP komt er vrij bij oxidatieve fosforylering?
De citroenzuurcyclus levert 2 ATP op, 6 NADH die in de oxidatieve fosforylering 18 ATP opleveren en 2 FADH2 die in de oxidatieve fosforylering 4 ATP opleveren. Hieruit volgt dat de complete aerobe dissimilatie 38 ATP oplevert, in theorie tenminste.
Why is ATP 36 or 38?
Why is ATP 36 or 38? According to some of newer sources the ATP yield during aerobic respiration is not 36–38, but only about 30–32 ATP molecules / 1 molecule of glucose , because: ATP : NADH+H+ and ATP : FADH2 ratios during the oxidative phosphorylation appear to be not 3 and 2, but 2.5 and 1.5 respectively.
Why does Glycolysis only produce 36 net ATP?
That’s not why. The 2 ATP you use as input early on in glycolysis can still be counted and you can still get 38 net ATP produced through aerobic oxidation of one glucose molecule. The reason it’s typically 36 for eukaryotes is that transport of the glycolytically-produced NADH into the mitochondria often takes 1 ATP each.
Why is the actual yield of ATP lower than theoretical?
Why is the actual yield of ATP during aerobic respiration lower than the theoretical yield of 38 ATP molecules? Although the theoretical yield can be up to 38 ATP molecules per molecule of glucose, this yield is very rarely achieved. It is important to consider at which stages the losses of ATP occur and why.
How many ATP can be made from one glucose molecule?
Biology textbooks often state that 38 ATP molecules can be made per oxidized glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system). Why is ATP 36 or 38?
Hoe vorm je ATP?
ATP is de drager van chemische energie en wordt gevormd door de binding van ADP aan anorganisch fosfaat (Pi). De energie die nodig is voor deze koppeling komt uit verbranding van organische verbindingen of uit fotosynthese.
Waaruit is ATP opgebouwd?
ATP is een organische verbinding bestaande uit de nucleobase adenine, de monosacharide ribose en drie fosfaatgroepen. In de bindingen tussen de fosfaatgroepen zit veel energie opgeslagen, en deze energie zal vrijkomen wanneer een fosfaatgroep wordt afgesplitst.
