What chemical compound provides energy for cells?

adenosine triphosphate

Explanation:

Energy Metabolism and ATP Synthesis in Human Cells

In most animal cells, adenosine triphosphate (ATP), a compound with high potential energy, works as the main carrier of chemical energy.

Adenosine triphosphate (ATP) is a complex organic chemical that provides energy to drive many processes in living cells, e.g. muscle contraction, nerve impulse propagation, and chemical synthesis. Found in all forms of life, ATP is often referred to as the "molecular unit of currency" of intracellular energy transfer.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
