Exothermic

More like exothermic... The two terms are somewhat confusing.

"that would demonstrate exothermic/endothermic rather than exergonic/endergonic." Good point, the cold pack is not an appropriate demonstration of an endergonic system as there is an increase of entropy from mixing.

that would demonstrate exothermic/endothermic rather than exergonic/endergonic. I am afraid there is no simple way to show exergonic/endergonic reactions since deltaG is a quantitative sum of enthalpy and entropy. Maybe an explosion ...

... and run the reaction in reverse, synthesizing ATP. That's because an enzyme works both ways, it is just a catalyst. Of course, ATP hydrolysis is exothermic and the concentrations favor the forward reaction in vivo. However, in vitro, I would dare to say that you can make pretty much every ATPase ...

... requires an enzyme to proceed. b) the reaction is non-spontaneous. c) the reaction requires energy to proceed. d) this reaction is exergonic (exothermic). e) none of the above statements must be true. Answer A as a correct is obvious, but the answer C is also correct. Enzymes lower activation ...
