How do cells use the ATP cycle shown in the figure above?
statuscvo [17]

ATP is the energy coin of the cell. The hydrolysis of ATP releases energy which is used to carry out cellular functions.

  • The cells use the cycle to recycle ADP and phosphate.

  • The cross-bridge cycle of ATP involves its dephosphorylation,  thereby producing Adenosine diphosphate (ADP) and inorganic phosphate (Pi).

  • The ATP cycle involves an exothermic reaction (hydrolysis) that releases energy, which is used for the cells to carry out their metabolic functions (e.g., growth, differentiation, etc).
