Chemical work such as the endergonic process of polymerization. Nucleotide with unstable phosphate bonds that the cell hydrolyzes for energy to drive endergonic reactions. How ATP performs work Exergonic hydrolysis of ATP is linked with endergonic processes by transferring a phosphate group to another molecule. Phosphate transfer is enzymatically controlled. The regeneration of ATP ATP is continually regenerated by the cell.
Reaction is endergonic.
Energy to drive the endergonic regeneration of ATP comes from the exergonic process of cellular respiration. Enzymes A. Enzymes speed up metabolic reactions by lowering energy barriers Free energy change indicates whether a reaction will occur spontaneously, but does not give information about the speed of reaction. Biochemical reactions require enzymes to speed up and control reaction rates. Biological catalysts made of protein. Energy profile of an exergonic reaction 1.
