Final answer:
ATP stands for Adenosine Triphosphate. It is the 'energy currency' of the cell and is used to store and transfer energy for various cellular processes.
Step-by-step explanation:
ATP stands for Adenosine Triphosphate. Adenosine triphosphate is a nucleotide composed of adenine base bonded to ribose sugar and three phosphate groups. It is often referred to as the 'energy currency' of the cell because it is used to store and transfer energy for various cellular processes. The high-energy bonds between the phosphate groups in ATP release energy when broken, powering cellular reactions and processes.
