The triose phosphates are oxidised (lose hydrogen) forming 2 molecules of pyruvate. Coenzyme NAD+ (a co-enzyme is a helper molecule that carries chemical groups or ions around) collects the hydrogen ions forming 2reduced NAD (NADH + H+)4ATP are produced, but 2 were used up at the beginning so there is a net gain of2ATP. Overall,2 molecules of pyruvate and a small yield of ATP and reduced NAD are produced.
what is the difference between nad+ and nad because in the book it states nad to reduced nad but i see nad+ on the internet
NAD+ + H+ + 2e- +> NADH (i.e. reduced NAD)
