Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the end product of glycolysis given 1 molecule of glucose?
A
2 ATP, 4 NADH, 2 pyruvate
B
2 ATP, 2 NADH, 2 pyruvate
C
2 ATP, 2 NADH, 4 pyruvate
D
4 ATP, 2 NADH, 2 pyruvate
Explanation: 

Detailed explanation-1: -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).

Detailed explanation-2: -The end products of glycolysis are 2 pyruvate molecules, 2 ATP molecules, and 2 NADH molecules. A pyruvate molecule is a 3-carbon molecule. The glycolysis will produce 2 pyruvate molecules since it starts with a 6-carbon molecule (which is glucose). The process will also produce 2 ATP molecules and 2 NADH molecules.

Detailed explanation-3: -Explanation: 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.
