Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How much ATP is produced during the ETC?
A
2
B
4
C
32
D
34
E
36
Explanation: 

Detailed explanation-1: -The electron transport cycle generates around 30–32 ATP molecules, according to a recent study. This NADH consequently produces one to two ATP.

Detailed explanation-2: -The electron transport chain is located on the inner membrane of the mitochondria. The electron transport cycle yields around 30-32 ATP molecules, according to current studies.

Detailed explanation-3: -So, in aerobic respiration, a total of 38 molecules of ATP are created, with 2 ATP molecules formed outside the mitochondria. Electron transfer from glycolysis’ NADH and FADH2 molecules, pyruvate transformation, and the Krebs cycle generates up to 32 additional ATP molecules.

Detailed explanation-4: -When a single glucose molecule is broken down in aerobic cellular respiration, about 30-32 ATP molecules are produced within the cell. The number depends on the type of cell that we are considering.

Detailed explanation-5: -Cellular respiration produces 30-32 ATP molecules per glucose molecule. Although most of the ATP results from oxidative phosphorylation and the electron transport chain (ETC), 4 ATP are gained beforehand (2 from glycolysis and 2 from the citric acid cycle).
