Which of the following is the correct sequence of glycolysis?
Options
- AG 6-P → PEP → 3-PGAL → 3-PGA
- BG 6-P → 3-PGAL → 3-PGA → PEP
- CG 6-P → PEP → 3-PGA → 3-PGAL
- DG 6-P → 3-PGA → 3-PGAL → PEP
Correct answer
B. G 6-P → 3-PGAL → 3-PGA → PEP
Step-by-step solution
In glycolysis, glucose and fructose are phosphorylated to form glucose-6-phosphate by the activity of enzyme hexokinase and then converted to fructose 1-6 biphosphate which splits into 3C PGAL and DHAP . In subsequent steps, these products get oxidized to form PGA and then PEP, which at the end produces pyruvic acid, the end product of glycolysis.
