Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of these is not a phase of glycolysis?
A
Production of CO2
B
Cleavage (breaking bond in glucose)
C
Energy Investment
D
Energy Release
Explanation: 

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

Detailed explanation-2: -Carbon dioxide is not produced during glycolysis. Remember in glycolysis one glucose molecule yields 2 pyruvate, 2 ATP, and 2 NADH. Heat is also given off in form of energy as we went over before. Carbon dioxide is involved in other processes.

Detailed explanation-3: -In most cells glycolysis converts glucose to pyruvate which is subsequently oxidized to carbon dioxide and water by mitochondrial enzymes. However, in some cells, most notably mature red blood cells, glycolysis is the only means of ATP production because of the lack of mitochondria.

Detailed explanation-4: -The three-carbon molecule that is the final product of glycolysis is pyruvate.

Detailed explanation-5: -Stage 1 (Priming stage) Stage 2 (Splitting stage) Stage 3 (Oxidoreduction-phosphorylation stage) Energy Balance Sheet for glycolysis.
