Answer #1

THE FUNCTION OF ATP IN MAINTAINING THE RESTING MEMBRANE POTENTIAL

  • Resting membrane potential is the electrical potential energy that result from the separating opposite charges across the plasma membrane, when those charge are not stimulating by the cell. the inside of the cell more negative than outside.
  • NA+- K+ ATPase pumps - this pump pushes only 2 K+ into the cell for every 3 NA+ ​​​​​​it pumps out of the cell therefore, it activity result in a net loss of positive charge in the cell

THE FUNCTION OF ATP DURING THE CONDUCTION OF THE ACTION POTENTIAL

  • The action potential starts and the beginning of the axon and flows down into the synaptic bulb where it forms into neurotransmitter vesicles that release the transmitter through the end of the synaptic bulb on to the target cell
  • The NA+ / k+ pumps illustrates " active transport" since it moves NA+ and K+ against their concentration gradient that is because there is high concentration of NA+ outside the cell, in order to move NA+ / K + ions against the gradient, energy is required. This energy is supplied by ATP.
