First of all: I keep finding two equations that are supposedly showing the same reaction:
1) NAD+ +2e +H+ -> NADH
2) NAD+ +2e +2H+ -> NADH +H+
The first one suggests NAD carries around 2 electrons and one hydrogen ion
The second one suggests NAD carries around 2 electrons and 2 hydrogen ions
I imagine that the second equation shows an extra H+ ion (when compared to the first one) because for some reason a H+ ion follows the NADH around. Is it because a H+ ion forms a co-dative bond with the NADH (allowing it to 'carry' around 2 H+ ions?).
If the second H+ doesn't form a codative bond with the NADH, then what kind of bond does it form that allows it to follow the NADH around instead of just diffusing away?
