ATP & High Energy Compounds

High energy compounds or energy rich compounds is usually applied to substances in the biological system which on hydrolysis yield free energy equal to or greater than that of ATP i.e. ∆G= -7.3 kcal/mol

 ATP acts as an energy link between catabolism (exergonic reactions) and anabolism (endergonic reactions) • Catabolic reactions give energy, in the form of ATP. • Anabolic reactions can utilize energy through hydrolysis of ATP
