These proteins are activated or deactivated by phosphorylation (adding of a phosphate group using ATP), in response to neurotransmitters and growth factors.

Then it puts together its own organic compounds using ATP.

Living cells use ATP as the most important direct energy source.

This increase in calcium activates calcium-sensitive contractile proteins that then use ATP to cause cell shortening.

Together with aldose reductase, it provides a way for the body to produce fructose from glucose without using ATP.

Every cell uses ATP for energy.

The latter is the enzyme that uses ATP to phosphorylate and inactivate the actin-depolymerizing factor cofilin.

The substrate is taken in one side of the gated carrier, and without using ATP the substrate is released into the cell.

Metabolic processes that use ATP as an energy source convert it back into its precursors.

Other researchers are using ATP to treat metastatic cancer.
