|
Phosphorylation of fructose-2-phosphate
|
|
Cleavage of fructose 1, 3-diphosphate
|
|
Oxidative Phosphorylation of 6-phosphate
|
|
ATP is generated.

Explanation:
Detailed explanation-1: -Key Points. ATP molecules donate high energy phosphate groups during the two phosphorylation steps, step 1 with hexokinase and step 3 with phosphofructokinase, in the first half of glycolysis.
Detailed explanation-2: -The third step of glycolysis is the phosphorylation of fructose-6-phosphate, catalyzed by the enzyme phosphofructokinase. A second ATP molecule donates a phosphate to fructose-6-phosphate, producing fructose-1, 6-bisphosphate and ADP as products.
Detailed explanation-3: -During glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi–> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O).
