Detailed explanation-1: -Therefore, the sodium-potassium pump is an electrogenic pump (a pump that creates a charge imbalance) contributing to the membrane potential. What will happen to the opening of the sodium-potassium pump if no ATP is present in a cell? It will remain facing the extracellular space, with sodium ions bound.
Detailed explanation-2: -area with lower concentration. The difference between the concentrations is called the “concentration gradient”. Diffusion goes down the gradient until an equilibrium is reached.
Detailed explanation-3: -Active transport moves molecules and ions from lower concentration to higher concentration with the help of energy in the form of ATP. On the other hand, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.
Detailed explanation-4: -Simple diffusion does not require energy: facilitated diffusion requires a source of ATP.
