Botany - Respiration in Plants Question with Solution | TestHub

In aerobic respiration complete oxidation of one glucose molecule produces 38 ATP molecules. But the

number of ATP molecules so produced may vary depending upon the mode of entry of NADH 2 in the

mitochondria. If the electrons of NADH 2 are accepted by malate then each molecule of NADH 2 yields 3 ATP molecules and the total would be 38 ATP molecules. But if the electrons of NADH 2 are accepted by FAD it yields only 2 ATP molecules making the total of 36 ATP molecules. This type of shuttle occurs in most of the eukaryotic cells.
