Anatomy and Physiology, Energy, Maintenance, and Environmental Exchange

Polysaccharides serve as energy storage (e.g., starch and glycogen) and as structural components (e.g., chitin in insects and cellulose in plants). When the environment is not thermoneutral, the body uses four mechanisms of heat exchange to maintain homeostasis: conduction, convection, radiation, and evaporation. Each of these mechanisms

2.3 Chemical Reactions – Anatomy & Physiology

Potential energy is the energy of position, or the energy matter possesses because of the positioning or structure of its components. If the brick wall collapses, the stored potential energy is released as kinetic energy when the bricks fall. In the human body, potential energy is stored in the bonds between atoms and molecules.

Why is ATP the preferred choice for energy carriers?

$begingroup$ I think this answer mixes up the advantage of phosphates as energy carriers with the predominance of ATP. The case for phosphates is nicely made by Westheimer''s 1987 paper; but there is little reason to suppose that ATP is chemically special compared to, say, GTP --- the prevalence of ATP over other triphosphates is likely just an
