The net gain of ATP during glycolysis is

Options

A. Six
B. Eight
C. Two
D. Four

Answer

C

Explanation

The net gain of ATP in glycolysis is 2ATP molecules.ATP Produced –
* `{:("1,3Bisphosphoglycerate"),(" ( 2 Mol)"):} undersetunderset("Kinase")("Phosphoglycerate")overset(ADP rarr ATP)rarrunderset(("2 Mol"))("3Phosphoglycerate")`
* Phosphoenol Pyruvate `underset("Pyruvatekinase")overset(ADP rarr ATP)rarrunderset(("2 Mol"))("Pyruvate")`
ATP Consumed –
* `underset("1 Mol")("Glucose ")underset("Hexokinase") overset(ADP rarr ATP)rarr underset((" Mol 1"))(" Glucose 6 Phosphate")`
* `underset("(1 Mol)")("Fructose 6 Phosphate") undersetunderset("Kinase")("Phosphofructo")overset(ADP rarr ATP)rarrundersetunderset(("1 Mol"))("Bisphosphate")("Fructose1,6")`
Net ATP produced = ATP – ATP
Produced Consumed = 4 – 2 = 2ATP
