So in answering number 34 I'm also going to answer number 33 about coupled reactions. So a reaction is coupled to another reaction. If the two reactions have a substance in common and that substance in common is referred to as a common intermediate in the case, In the case of a teepee, it's often couple to a reaction that involves phosphate. And, uh, so what happens is that going on to number 34 in a process a phosphor relation process such as the phosphor relation of glucose to produce glucose six phosphate? Um, that is a non spontaneous process. Ah, but if ah, the hydraulics ISS of 80 p can be coupled to a non spontaneous reaction, then the reaction that is the sum may have a negative Delta G zero and be spontaneous. And it doesn't really matter that as the reaction happen biologically, there really isn't any ah free phosphate involved. Instead, the's the reaction here that is, that some is also the mechanistic reaction. The phosphate is transferred directly from the 80 p to the glucose. Ah, but it doesn't matter. Uh, that ah phosphor relation of glucose would be spontaneous with it would be non spontaneous without a teepee, but the energy that is released in the hydraulics ISS of 80 p. You will go together with the free energy change for another reaction involving phosphate to produce a spontaneous reaction. So the role of 80 p is to is for its hydraulics ISS to provide free energy to make otherwise non spontaneous processes be spontaneous and to occur.
