neuroscience - What is the energy cost of an action potential?


As I understand it, ions flow down their electrochemical potentials through ion channels during a neuron's action potential. Otherwise, ion pumps work to restore and maintain the resting membrane potential. What is the energy cost of a neuron's action potential? That is, how much work must the ion pumps perform to restore the resting membrane potential after an action potential occurs?

evolution - Are there any multicellular forms of life which exist without consuming other forms of life in some manner?

The title is the question. If additional specificity is needed I will add clarification here. Are there any multicellular forms of life whic...
