Question

the net yield of oxidation of 1 glucose molecule via glycolysis is ______ atp. enter a whole number
numeric response

Explanation:

Step1: ATP used in glycolysis

In the preparatory phase of glycolysis, 2 ATP molecules are used (1 ATP for the conversion of glucose to glucose - 6 - phosphate and 1 ATP for the conversion of fructose - 6 - phosphate to fructose - 1,6 - bisphosphate).

Step2: ATP produced in glycolysis

In the pay - off phase, 4 ATP molecules are produced via substrate - level phosphorylation (2 molecules of 1,3 - bisphosphoglycerate are converted to 3 - phosphoglycerate, each yielding 1 ATP; and 2 molecules of phosphoenolpyruvate are converted to pyruvate, each yielding 1 ATP).

The net yield of ATP is calculated as \(4 - 2\).

Answer:

2
