Which reaction or reactions in the scheme of glycolysis show

Which reaction or reactions in the scheme of glycolysis shown below is/are \"energy capture\" steps? (Shown Below)

A.) A and C B.) E and H C.) D, E and H   D.) A, C and D

Glucose Glucose-6-phosphate Fructose-6-phosphate Fructose-1,6-bisphosphate Glyceraldehyde Dihydroxyacetone phosphate 3-phosphate 1,3-bisphosphoglycerate 3-phosphoglycerate 2-phosphoglycerate Phosphoenolpyruvate Pyruvate Acetyl-CoA acetate Citrate Malate

Solution

Option B is correct.

Because in glycolysis one of the energy capturing steps is E that is formation of 3 phosphoglycerate from 1,3 bisphosphoglycerate with the help of enzyme phosphoglycerate kinase in this step 2 ATPs are generated.

Another energy capturing step is formation of pyruvate from phosphoenolpyruvate with the help of enzyme pyruvate kinase here also 2 ATPs are generated.

Hence option B is correct.
