Do all cells use ATP?
Posted September 16, 2022
Yes, all cells use ATP (adenosine triphosphate).
ATP molecules are the main energy source of all cells and are used for most cellular processes including active transport, DNA and RNA synthesis, nerve impulse transmission, muscle contraction, and structural maintenance among others.
ATP molecules are composed of a nitrogenous base (adenine), three serially bonded phosphate groups, and a ribose sugar. These compounds play a vital role in cellular metabolism, providing the energy necessary for both endergonic and exergonic processes.
Without the energy provided by ATP, some cellular processes would cease and the cell would eventually die.
