Answer:
ATP
Step-by-step explanation:
In break down of one molecule of glucose, the number of energy molecules gained at different level are as follows-
a) Glycolysis - 2 ATP are gained
b) Citric acid cycle- 2 ATP are gained
c) Electron transport chain- 34 ATP are gained (inclusive of conversion of NADH and FADH2 in terms of ATP , where on NADH is equal to 2 ATP molecule and one FADH2 is equal to one ATP molecule.)
Thus, total number of ATP gained from one cycle of break down of glucose
ATP
