ATP is necessary for the sodium potassium pump to complete its job. Is this an example of active or passive transport? Explain your answer.

Hello, please answer the following Physiology question completely and correctly. Thank you.  Physiology Question: "Explain the difference between facilitated diffusion and active transport. Further explain the difference between primary and secondary active transport."                         "

Explain why, when a concentration gradient exists on two sides of membrane, that the spontaneous movement of solute molecules is from areas of high concentration towards low concentration. (hint: think of thermodynamics)

If a skeletal muscle has depleted its stores of ATP how will the altered transport properties of the following transporters affect cytosolic ion concentrations (increase, decrease, no change) relative to normal?   Skeletal Muscle Cell With Depleted ATP Stores Ion transporter Cytosolic K+ Cytosolic Na+ Cytosolic Ca2+ NKA         NCX         SERCA
