Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which is not an output of Glycolysis?
A
NADH
B
ATP
C
O2
D
Pyruvate
Explanation: 

Detailed explanation-1: -In glycolysis, the six-carbon sugar glucose is converted to two molecules of pyruvate (three carbons each), with the net production of 2 ATP and 2 NADH per glucose molecule. There is no O2 uptake or CO2 release in glycolysis.

Detailed explanation-2: -Output of glycolysis is two molecules of pyruvate, adenosine triphosphate (ATP), nicotinamide adenine dinucleotide (NADH) and water. Glycolysis occurs in both aerobic and anaerobic organisms. When oxygen is absent pyruvate is converted to lactic acid or ethanol and CO2 by fermentation.

Detailed explanation-3: -Oxygen is neither a product nor reactant in glycolysis. Glycolysis is unique in that it takes place within the cytoplasm of the cell and does not require oxygen. It is an anaerobic reaction that produces pyruvate, NAD, and ATP.

Detailed explanation-4: -The output involved in glycolysis is four ATP, two NADH (nicotinamide adenine dinucleotide hydrogen) and two pyruvate molecules.
