bioenergetics

1. Biochemistry. The study of the flow and transformation of energy in and between living organisms and between living organisms and their environment.
2. Psychology. A therapeutic approach that incorporates breathing, movement, body exercises, psychotherapy, and free expression of feelings to enhance self-awareness and well-being and relieve physical and emotional tension.

The study of the flow and the transformations of energy that occur in living organisms. Typically, the amount of energy that an organism takes in (from food or sunlight) is measured and divided into the amount used for growth of new tissues; that lost through death, wastes, and (in plants) transpiration; and that lost to the environment as heat (through respiration).

The study of energy transformations in living organisms.

Section of biochemistry concerned with the mechanisms whereby the energy made released from the oxidation of substrates or the absorption of light can be used to drive thermodynamically unfavorable reactions such as the synthesis of ATP from ADP and Pi, or the accumulation of ions across membranes.
