WebYou know that NAD + is reduced by this process because it starts off with a positive charge (+1) and ends up with a neutral charge (0). The reducing agent that is donating the electrons is the hydrogen. More correctly, the … WebNotice that NADH does not carry the “plus sign”. This is because the negatively charged hydrogen molecule cancels the positively charged NAD+ molecule. Once NADH arrives at the enzymes, they drop off their negatively charged electrons and expel the hydrogen atom, subsequently becoming NAD+ again. The rest is taken care of by the enzymes. WebThe substrate must be held very close to the NAD+/NADH cofactor for the hydride transfer to take place, and this is made possible by the preorganization of the enzyme. This is accomplished in a very specific manner, where the substrate and face of the NAD+/NADH cofactor are held in very specific orientations. chinese dried fish powder
