Question

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

Answer 1

Biology textbooks often state that 38 ATP molecules can be made per oxidisedglucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).

Answer 2

Answer:

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

$= 4+4+34\\= 38$ATP
