Hello, After going over my biochemistry chapter on glycolysis, the TCA cycle and the electron transport chain, it seems to me like the only role that Krebs plays (in the context of ATP generation I mean) is to produce enough H+ and electrons to fuel the electron transport chain mechanism. Is there any other point to it? Are all reactions in Krebs specifically intended to cause as many oxydations as possible to feed the ETC? Should krebs be seen in that perspective? Thanks in advance. PS: What I'd like is to understand is the point behind all those reactions and why they happen the way they happen.
