Question

how many ATP in glycolysis​

Answer 1

Answer:

2 ATP

Explanation:

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). The hydroxyl groups allow for phosphorylation. The specific form of glucose used in glycolysis is glucose 6-phosphate.

Hope it helps.

Answer 2

Answer:

During glycolysis a glucose molecule is broken to release 4 ATP molecules with expenditure of 2 ATP molecules.

Hence a net gain of 2 ATP molecules per glucose molecule broken
