NAD plus
NAD+ accept electrons.
NAD+ is a CO-enzyme.
A. both NAD plus and FAD
NAD+ is reduced. It becomes NADH.
NAD+ is the oxidized and NADH is the reduced form.
NAD+ isn't oxidised, it can be reduced by H to form NADH
Substrate.
if NAD+ is not availabe, glycolysis will stop and the cell will DIE
Electrons. ( plus that proton )
Fermintation
If NAD+ is not regenerated, the oxidation of glyceraldehyde 3-P will cease and glycolysis will stop.
