lab quiz 3 Flashcards
dialysis tubing
tightly packed cellulose fibers with numerous small pores (size can be altered to let specific molecules through)
normally, large molecules (____ and larger) and highly charged molecules (such as ___) have a hard time passing through dialysis tubing
disaccharides; ions
diffusion is active or passive
passive movement since molecules want to spread out
isosmotic
the concentration of solutes is equal on both sides of a membrane, resulting in no net movement of water across the membrane.
hyperosmotic
the concentration of solutes is higher inside the cell, causing water molecules to move from the side with lower solute concentration to the side with higher solute concentration.
hyposmotic
the concentration of solutes is lower inside of the cell, causing water molecules to move from the side with higher solute concentration to the side with lower solute concentration
osmotic deals with ___, tonic deals with ___
cell, solution
osmotic deals with ___, tonic deals with ___
