Detailed Solution

Concept: The primary goal of glycolysis, which begins with the breakdown of glucose into pyruvic acid and energy with the aid of an enzyme, is to produce pyruvate for the TCA cycle.
The glycolysis is the conversion of pyruvic acid and energy from glucose. In order to create fructose 1,6-bisphosphate, two phosphorylation reactions require the use of two ATP molecules. In exchange, a substrate-level phosphorylation reaction that converts 1, 3-bisphosphoglycerate to 3-phosphoglycerate and phosphoenolpyruvate to pyruvate produces four ATP molecules. During the conversion of 1,3-diphosphoglycerate from glyceraldehyde 3-phosphate to NADH2, two molecules are created.
Complete reaction of glycolysis is:
Glucose + 2NAD+ +2ADP+2H3PO4→ 2pyruvic acid+2ATP+2NADH2
Hence, the correct answer is option 1.
