NAD+

NADH
|
Explanation:
Detailed explanation-1: -When NAD+ takes an electron from glucose, it becomes NADH, the reduced form of the molecule. NADH transports this electron to mitochondria where the cell can take the energy that is stored in the electron. NADH then donates the electron to oxygen, converting it back to NAD+.
Detailed explanation-2: -NADH is actively carrying electrons and NAD+ is not carrying electrons. NADH is the reduced form of NAD+. NAD+ is the oxidized form of NADH.
Detailed explanation-3: -NADPH is the reduced form of NADP+. NADP+ differs from NAD+ by the presence of an additional phosphate group on the 2’ position of the ribose ring that carries the adenine moiety.
Detailed explanation-4: -NADPH reduced form tetrasodium salt.
