How do you do this?
Equilibrium means all of the following except
(which is false?)
the concentration gradient for a solute is the same on either side of the membrane.
molecules are in equal concentration and therefore no longer move across the membrane.
there is no net movement molecules across a membrane.
the water concentration is equal on either side of the membrane.
When two chambers are separated by a membrane permeable to water but not solute, if water is free to move in either direction without limitation or pressure, then water will
move until the concentration of solute on both sides of the chamber is equal
move until there is no water on the dilute side
move until there is no water on the concentrated side
move until the concentration of water on both sides of the chamber is equal

- When the net charge on either side of the plasma membrane is zero, what else is true? There is an equal number of K+ ions on each side of the plasma membrane. The K+ leak channels are open. The electrochemical potential across the membrane is zero. The resting membrane potential is between -20 mV and -200 mV.arrow_forwardWhich of the following statements regarding the equilibrium potential (Eion) of an ion is correct? The equilibrium potential for potassium is less negative than the resting membrane potential. The electrical force that acts upon potassium attracts potassium to the interstitium. The chemical force that acts upon sodium drives sodium out of the cell. At an ion’s equilibrium potential, the electrochemical force is zero.arrow_forwardSolutes tend to diffuse from a region where they are _______ more/less concentrated to an adjacent region where they are ________ more/less concentrated.arrow_forward

The temperature is 25 C.arrow_forwardWhich of the following statements is TRUE of diffusion? Diffusion of particles along the concentration gradient will occur until particles are equally distributed in all areas of the solution. Diffusion of particles along the concentration gradient will occur until the particles move fully from one side of the solution to the other. Diffusion of particles against the concentration gradient will occur until random motion occurs. Diffusion of particles against the concentration gradient will occur until all the particles have dissolved. Carl is examining an onion root tip cell under a microscope.

For a given concentration gradient of an ion, the equilibrium potential is the charge inside the cell required to hold an ion at that concentration. That is, it is the charge required to perfectly oppose the drive of the ion to move down its concentration gradient. So, if the concentration of Nat is higher outside the cell than inside, its equilibrium potential (ENa) must be I and if we add more sodium to the extracellular fluid, then ENa will II.arrow_forward
