Each acetyl CoA entering the citric acid cycle produces two CO2, three NADH, one FADH2, and one GTP (converted directly to ATP in the cell). Taking into consideration the conversion of reduced nucleotides to ATP, what is the total number of ATP produced by one glucose (2 Acteyl CoA) going through the citric acid cycle?
