# Which molecule is produced when two electrons and one proton are added to NADP^+?

Mar 20, 2016

The molecule produced is $\text{NADPH}$.

#### Explanation:

The structure of ${\text{NADP}}^{+}$ is

The positive charge is on the $\text{N}$ atom in the nicotinamide ring.

In biochemical reactions, ${\text{NADP}}^{+}$ acts as a "hydride" acceptor.

The hydride is not $\text{H"^"-}$, but its chemical equivalent, $\text{H"^+ + 2"e"^"-}$

The hydrogen atom adds to the nicotinamide ring, converting the molecule to $\text{NADPH}$.
