ATP (adenosine triphosphate), or ultimately it would be glucose.
Glycogen is the molecule stored in the liver for extra energy. When the body needs a quick source of energy, glycogen can be broken down into glucose to be used by the body's cells.
Adenosine triphosphate (ATP) is the immediate source of energy for cells. When ATP is broken down into adenosine diphosphate (ADP) and inorganic phosphate, energy is released that can be used by cells for various cellular processes.
Glucose is a molecule that can be used as a quick source of energy in the body. It is readily broken down in cells through a process called cellular respiration to produce ATP, the energy currency of the cell.
The energy source for phosphorylation in cells is often adenosine triphosphate (ATP). ATP is a molecule that stores and transfers energy within cells and is commonly used to add phosphate groups to other molecules, a process that drives many cellular reactions.
The molecule that is the primary source of energy in all cells is ATP, which is definitely not a macromolecule. The molecule that is the primary source of energy in cells for making ATP from ADP is glucose, which is definitely not a macromolecule. Macromolecules that can be metabolized for energy (starches, fatty acids, proteins) are only secondary or tertiary sources of energy as the process of extracting energy from them is slow and inefficient.
The primary source of energy used to form an ATP molecule is the breakdown of glucose through cellular respiration.

The chief energy currency all cells use is a molecule called ATP. ATP is the main energy source that cells use for most of their work adenosine.
The energy molecule used in animal cells is adenosine triphosphate (ATP). It is produced during cellular respiration and serves as a universal energy carrier in cells for various biochemical reactions.
