Question

Which is an example of a spontaneous exergonic reaction? A) Protein synthesis occuring in cells B) Marshmallows catching fire C) Photosynthesis

This is B), stuff wih marshmallows. The proteins synthesis needs energy to occur and does not give any form of energy in return, so do photosynthesis. On the contrary, when marshmallows catch fire, they burn and the burning sugar produces heat and energy : this is an exergonic reaction.
