The combination of important nutrients, shallow water and large primary productivity is basic source for Earth's food web.

what is meant by an atp cycle and why is it an important frequent event in cells? how does this involve adp
strojnjashka [21]

Answer:

Please find the explanation to this question below

Explanation:

The ATP cycle is the series of reactions involving glycolysis, Krebs cycle and oxidative phosphorylation that produces/synthesizes ATP in living cells. These processes collectively is called CELLULAR RESPIRATION. Glycolysis produces 2ATP molecules, Krebs cycle produces 2ATP while the electron transport chain (oxidative phosphorylation) produces 34ATP molecules.

This cycle of ATP as explained above is an important frequent event in cells because all organisms need energy to carry out their metabolic activities. ATP is the energy-carrying molecule that stores and releases energy for use by the cells, hence, it needs to be produced on a frequent basis.

ATP can be likened to a charged battery ready to release its stored energy. The energy is stored in the phosphate bonds that makes up its structure. When ATP releases its energy, it becomes ADP (Adenosine diphosphate). However, ADP is a reactant in the ATP cycle, which is phosphorylated with an inorganic phosphate (Pi) and catalyzes by ATP synthase to form ATP.
