What is the energy molecule of the cell called?

ATP, or Adenosine triphosphate

Explanation:

The energy molecule of a cell is called ATP (Adenosine triphosphate). Cells make this molecule through the process of cellular respiration. Cells use this ATP to transfer molecules and atoms across the cell membrane.

Adenosine 5'-triphosphate, or ATP, is the most abundant energy carrier molecule in cells. This molecule is made of a nitrogen base (adenine), a ribose sugar, and three phosphate groups.
