Sodium-potassium pumps Sodium-potassium pumps become inactivated for a short period of time once peak membrane potential is reached during an action potential. function continuously whether or not a neuron is sending signals. stop functioning at the beginning of an action potential and resume functioning once voltage-gated K channels close at the end of an action potential. only function when a neuron is at rest (not sending signals).

Abody cell has been growing and at synthesis proteins.in the nucleus of this body cell,dna replication is taking place. and a copy of the cells genetic material is copied.which of the following is the best conclusion you can make about the life cycle of this cell ? a) the cell is ready to undergo mitosis.and a chemical signal will send the cell to prophase b)the cell is undergoing meiosis and will cross over the genetic material next c)the cell is in the s phase of interphase and will move next to the g2 phase d) the cell is in the g2 phase of the interphase and is ready to begin diving
