The energy obtained by a cell from catabolic reaction is stored immediately in the form of ATP or adenosine triphosphate. ATP: The energy currency of the cellATP is a high-energy molecule that stores energy in its phosphate bonds. It is considered as the energy currency of the cell because it provides energy for various cellular processes. The ATP molecule consists of a nitrogenous base, adenine, a sugar molecule, ribose, and three phosphate groups. ATP synthesis: The process of ATP formationThe process of ATP formation is called ATP synthesis or phosphorylation. During cellular respiration, the energy obtained from the breakdown of glucose or other organic molecules is used to synthesize ATP. This process occurs in the mitochondria of eukaryotic cells and the cytoplasm of prokaryotic cells. ATP hydrolysis: The release of energy from ATPThe release of energy from ATP occurs when the terminal phosphate group is removed from the ATP molecule in a process called ATP hydrolysis. This releases energy that can be used for various cellular processes, such as muscle contraction, protein synthesis, and active transport. Conclusion:In summary, the energy obtained by a cell from catabolic reactions is stored immediately in the form of ATP. ATP serves as the energy currency of the cell, providing energy for various cellular processes. ATP synthesis occurs during cellular respiration, and the release of energy from ATP occurs through ATP hydrolysis.
