By which of the following mechanisms is energy generally extracted from phototrophs and chemotrophs?

Question

Quizplus · Accepted Answer

Energy is generally extracted from phototrophs and chemotrophs through oxidative-reduction reactions, which involve the transfer of electrons from a donor molecule to an acceptor molecule. This results in the generation of ATP, which is used as an energy source by cells. Hydrolysis reactions, condensation-cleavage reactions, and acid-base reactions can also be involved in energy metabolism, but they are not the primary mechanisms by which energy is extracted from phototrophs and chemotrophs.
