It's replaced by a phosphate group.

oh so where did the hydrogen atom go?

Might be the ones used later in NADH. The entirety of respiration relies heavily on hydrogen gradients so it might be part of that.

nah. the hydrogen atom becomes bound to ADP. the reduction of NADH becomes important later on.

Oh okay, thanks!
