Solution

The correct option is B 36 ATP
The ATP yield per unit of glucose catabolized is much lower under anaerobic conditions (2ATP/Glucose) than under aerobic conditions (36-38ATP/glucose). For a eukaryotic cell that uses the glycerol phosphate shuttle, and glycerol phosphate shuttle transfers electrons from NADH in the cytosol to FAD in the mitochondrion, the ATP yield per cytoplasmically generated ATP is 2 instead of 3, and the ATP yield is therefore decreased by 2 which gives total of 36 ATP's in eukaryotes.
