Wha is the function of NAD+ in glycolysis?

Answer 1

NAD+ picks up the electrons that are removed during glycolysis --> makes a molecule of NADH. This NADH goes to the electron transport chain where it gives up the electron to the electron transport chain.

Answer 2

Glycolysis undergoes a redox reaction. Molecules that gain electrons are reduced and those that lose electrons are oxidated. NADH donates a H+ proton during this process, therefore is oxygenated. These protons are then carried down to the electron transport chain, where it provides energy to make ATP. The end-product of the electron transport chain is 11 H2O molecules, the H2 stems from the donation of H+ protons from NADH.
