Source sentences:
text: In the simplest case, illustrated here, if the membrane is selectively permeable to potassium, these positively charged ions can diffuse down the concentration gradient to the outside of the cell, leaving behind uncompensated negative charges.
text: While the plasma and lysosomal membranes are permeable for neutral and uncharged species of weak bases, the charged protonated species of weak bases do not permeate biomembranes and accumulate within lysosomes.
text: The membrane is semi-permeable, and selectively permeable, in that it can either let a substance (molecule or ion) pass through freely, pass through to a limited extent or not pass through at all.
text: The membrane is semi-permeable, and selectively permeable, in that it can either let a substance (molecule or ion) pass through freely, pass through to a limited extent or not pass through at all.
text: This membrane is selectively permeable, which means that some chemicals ( such as water and oxygen) can move freely across the membrane, whereas other chemicals ( often large ones like proteins and DNA ) are blocked by the membrane.
text: The membrane is selectively permeable.
text: Animal cells have a membrane that is differentially permeable.
text: This structure causes the membrane to be selectively permeable.
text: At least one of the conformations creates a channel through the membrane that is permeable to specific types of ions.
text: Five dialysis bags constructed of membrane, which is permeable to water and impermeable to sucrose, were filled with various concentrations of sucrose and then placed in separate beakers containing an initial concentration of 0.6 M sucrose solution.
text: Assume that the membrane is permeable to water, but not to sucrose (represented by the small black squares).
text: This structure causes the membrane to be selectively permeable.
