A student is studying the diagram in figure 1 and notices that the reactions and cellular intermediates of photosynthesis and cellular respiration differ considerably. Understand how it's calculated and its relationship with enthalpy, temperature, and entropy. Dive into the concept of free energy change, activation energy, and how enzymes can speed up reactions

The activation energy shown in the diagram below is for the forward reaction (reactants → products), which is exergonic
If the reaction were to proceed in the reverse direction (endergonic), the transition state would remain the same, but the activation energy would be larger.
What would happen to the energy stored in the proton gradient if it weren't used to synthesize atp or do other cellular work It would be released as heat, and interestingly enough, some types of cells deliberately use the proton gradient for heat generation rather than atp synthesis. I've hopefully given you a bit of a gut feeling behind where the formula of gibbs free energy comes from In this video i want to do something a little bit more rigorous and actually, i guess you could say derive the formula.
Explore the concept of gibbs free energy and its role in spontaneous chemical reactions
