Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which is not part of the net products of Glycolysis?
A
2 ATP
B
2 NADH
C
2 Pyruvate
D
2 CO2
Explanation: 

Detailed explanation-1: -FADH is not produced during glycolysis.

Detailed explanation-2: -Glycolysis produces zero molecules of carbon dioxide.

Detailed explanation-3: -Carbon dioxide is an important side product of both glycolysis and the citric acid cycle (Krebs cycle). This oxidized carbon represents an end product of metabolism that, ultimately, needs to be removed using transport to the lungs and subsequent expiration out into the surrounding environment.

Detailed explanation-4: -Glycolysis creates ATP and NADH through substrate level phosphorylation. The net products are 2 ATP, 2 NADH, and 2 pyruvate molecules. More ATP and high energy electron carriers are produced in the subsequent stages of the metabolic pathway such as pyruvate processing and the citric acid cycle.

Detailed explanation-5: -During glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi–> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O).
