During metabolism, the complete breakdown of one molecule of glucose results in a maximum yield of 38 molecules of

ATP

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

the correct answer should be false
