Adenosine triphosphate (ATP) plays a central role in cellular metabolism as the primary energy currency. It stores and transports chemical energy within cells, enabling various biochemical reactions necessary for life. When ATP is hydrolyzed, it releases energy, powering cellular processes such as protein synthesis, muscle contraction, and active transport. Additionally, ATP acts as a signaling molecule in cellular pathways, influencing metabolism and regulating various physiological functions. It is vital for sustaining energy-dependent processes in all living organisms.
