Question

What is the name of the molecule that provides the energy that enables a muscle to contract? ?

Answer 1

ATP or adenosine triphosphate

Answer 2

ATP is the source of all energy in the cell.  Food is broken down until it can enter the Calvin cycle and electron transport chain (entering at various points, depending on the type of food), which ultimately leads to the production of ATP.
