Botany - Respiration in Plants Question with Solution | TestHub

Total NADH entering ETS is 10 (2 NADH from glycolysis, 2 NADH from link reaction, 6 NADH from Krebs' cycle. ATP formed from 1 NADH is 3. Thus ATP formed from 10 NADH is 30.

Total FADH2 entering ETS is 2 (from Krebs' cycle). ATP formed from 1${\mathrm{F}\mathrm{A}\mathrm{D}\mathrm{H}}_2$is 2. Thus, ATP formed from 2${\mathrm{F}\mathrm{A}\mathrm{D}\mathrm{H}}_2$is 4. Thus the ATP formed in ETS is 34 out of the total 38 produced by complete aerobic respiration of one molecule of glucose
