NAD+ accept electrons.
Electrons. ( plus that proton )
NAD+ is reduced. It becomes NADH.
NADH
to accept high energy electrons
the free energy liberated when electrons are removed from the organic molecules must be greater than the energy required to give the electrons to NAD+
They form FADH2 and NADH
They build up.
NADH+ provides electrons for the é transport chain.
Nadh is the reduced form of Nad+. Nad+ acts as a oxidizing agent and can accept electrons in various chemical reactions in the cell.
NAD (neutral compound) added to H(+), a positively changed proton, gives you NADH(+)
NAD+ is reduced. It becomes NADH.
