Energy transfer

Energy transfer

The transfer of energy of a given form among different scales of motion. In biochemistry, this concept generally refers to the transfer of groups from compounds that contain energy-rich bonding arrangements to compounds that have relatively energy-poor bonding characteristics via thermodynamically permissible enzymatic reactions. This principle is a major premise of the interaction between energy-producing and energy-utilizing metabolic pathways in living cells.

Re: Resonance transfer

Once case of resonance transfer is when an electron in an excited state drops to a more stable state and passes the energy to another electron, exciting that electron to a higher-energy state. An example of this with relevance ...
