Answer to Question #150114 in Cell Biology for batan

Question

Explain how ATP performs cellular work and explain why an investment of activation energy is necessary to initiate a spontaneous reaction

Answer 1

ATP is composed of three phosphate remains, and they are bounded with the biggest energy conserving bonds - phosphoanhydride, they are formed during break down processes such as respiration or glycolysis. If energy wont be stored in bonds, organism will lose it in heat dissipation, so it gained such mechanism in process of evolution

Reactions do not occur spontaneously, there is a need in some push for their beginning, and activation energy provides such push
