Question

If there are 4 molecules of glucose, how many ATP molecules would you produce in aerobic cell respiration?
A) 152
B) 8-10
C) 400
D) 25

Answer 1

Answer:

Option A, 152

Explanation:

One glucose molecule undergoes the following three process in one complete chain of aerobic cell respiration -

a) Glycolysis - 2 ATP molecules are produced

b) Kerb cycle - 2 ATP molecules are produced

c) Electron transport chain - 34 ATP molecules are produced

Hence one glucose molecule can produce 38 ATP molecule

Therefore 4 glucose molecule produce

$38 * 4\\= 152$ ATP molecules

Hence, option A is correct.

Answer 2

Answer:

A) 152

Explanation:

Aerobic respiration involves the breakdown of glucose in the presence of oxygen to produce carbon dioxide, water and energy in the form of ATP.

Theoretically, 38 molecules of ATP is yielded from one molecule of glucose during aerobic cellular respiration.

Hence, if 1 molecule of glucose produces 38 molecules of ATP;

4 molecules of glucose will produce: 4 x 38 = 152 molecules ATP

The correct option is A.
