Which of the following steps during glycolysis is associated with utilization of ATP?
Options
- AGlucose → Glucose-6-phosphate
- BFructose-6-phosphate → Fructose-1, 6-biphosphate
- CPEP → Pyruvic acid
- DBoth A and B
Correct answer
D. Both A and B
Step-by-step solution
Glycolysis is the process of breakdown of glucose to extract energy for cellular metabolism. It takes place in the cytosol of a cell. Pyruvic acid is the key product of the process of glycolysis. 1 molecule of Glucose (6C) undergoes phosphorylation with the help of ATP to form 1 molecule Glucose-6-phosphate (6C) in the presence of enzyme Hexokinase and Magnesium ions as cofactor. 1 molecule of Fructose-6-phosphate (6C) undergoes phosphorylation with the help of ATP to form 1 molecule of Fructose 1,6-diphosphate (6C
