The following are the requirements for glycolysis to occur in the cytoplasm EXCEPT:

Explanation

The correct answer is option D: FAD. FAD is not involved in glycolysis; it plays a role in the citric acid cycle and the electron transport chain. Glycolysis, occurring in the cytoplasm, requires glucose as the starting molecule, ATP for energy investment and generation, and specific enzymes and coenzymes such as NAD+ to facilitate the series of reactions. Although ATP, glucose, enzymes, and coenzymes are directly involved in glycolysis, FAD is not.
