In Figure 8.10, the energetic coupling of substrate phosphorylation and an endergonic reaction are shown. If the hydrolysis of ATP releases 7.3 kcal of free energy, use the graph in this figure to estimate what you would expect the ∆G values to be for the uncoupled reaction and the two steps in the coupled reaction.

Hello everyone. So today we have a fairly short video. So let's just jump straight into the problem. So energy coupling is a concept in which energy released by a blank reaction is used to drive a blank reaction. So the main concept that we need to understand here are ex organic and and organic. So an ex organic reaction releases energy while an end organic reaction takes up energy. So since this eggs organic reaction is going to release energy, we can use that energy released to drive an undergone IQ reaction. And the reason for this is that since this energy is going to be available for use, it can be taken up by the end organic reaction in in order to drive itself. So the answer choice that is going to correlate with this is going to be answer choice B extra chronic and and organic. I really hope this video helped you and I hope to see you on the next one.
