Another molecule of citric acid from the same glass of lemon juice is converted to oxaloacetate, which is subsequently processed into glucose.How many molecules of ATP and/or GTP do the reactions from citrate to oxaloacetate produce, either directly or indirectly through the respiratory chain?

Question

NADH is produced by isocitrate dehydrogenase, α-ketoglutarate dehydrogenase, and malate dehydrogenase.Flavin adenine dinucleotide (FAD) is produced by succinate dehydrogenase, and GTP by succinyl-CoA synthetase.Assuming an ATP yield of three molecules for NADH and two for the reduced form of flavin adenine dinucleotide (FADH₂), this adds up to 11 ATP and 1 GTP.
