It is worth noting that these ATP values are maximums, in reality each NADH molecule contributes between 2 and 3 ATP, while each FADH 2 contributes a maximum of 2 ATP. Reactive oxygen ...

Protein

However uncertainties in the term of the equation make it impossible to predict whether life is rare or common. Another associated ...
