For a neuron to function, an input of free energy from ATP is required to set up the sodium and potassium ion concentration grad
Vlad [161]

Answer:

The lack of ATP would slow nerve responses to generate an action potential

Explanation:

Adenosine triphosphate (ATP) is the main source of energy in the cells. Moreover, ATPases are pumps that use ATP in order to transport sodium and potassium ions across the cell membrane and thus create an action potential. In stressful situations (e.g., escape from a predator) the lack of ATP would not allow to develop fast nerve responses, thereby ATP is required during rest periods and the flow of ions is used when is required a fast response.
