I understand that animals and plants break chemical bonds (e.g. Glycolysis in plants) in order to access energy.

What I haven't been able to find answer for is, how would kinetic/thermal energy produced by the breaking of a bond then be used to do something like, building a cellular wall, or myosins contracting in a muscle fibre?

The only thing that I can think of is the energy is then used for endothermic reactions to form different molecules? I don't understand how that could help in the muscle contraction scenario though.

Maybe this is actually many different answers, depending on the organism function in question, but hopefully someone can steer me in the right direction!
