QUIZ 5 Flashcards
small fragments that are diluted
Granules
it is the liquid
Solvent
involves the movement of solute in a solvent from an area of higher solute concentration to an area of lower solute concentration which eventually results in the state of dynamic equilibrium.
Diffusion
involves the movement of molecules in a solvent from an area of
higher solute concentration to an area of lower solute concentration which eventually results in the state of dynamic equilibrium.
Diffusion
● no energy required (gases)
● passive transport (labas /pasok)
● movement of molecules
● high to low concentration
● state of dynamic equilibrium
Simple diffusion
● dispersion
● dilute
● dilution
Diffusion
Molecules such as ions and water outside the cell are being transported across the cell membrane through channel proteins via facilitated diffusion
Facilitated Diffusion
● The channel protein facilitates the movement of molecules
● needs energy
Facilitated Diffusion
Movement of solvent is from the region of high water concentration to one with lower water concentration.
Osmosis
refers to the movement of water from higher to lower concentration
Osmosis
● concentration of balance between solute and solvent
● relative concentration of solutes in fluids
● depends on the concentration of solutes
● ability of a surrounding solution to cause a cell to gain or lose water
Tonicity
Solutions of equal solute concentration
Isotonic
is when water molecules move at the same rate in both directions.
Isotonic
● has lower solute concentration and has higher water concentration (10/90)
● outside is less than inside
Hypotonic
can cause the cell to swell or even burst due to the intake of water more than the cell can accommodate
Hypotonic
● has higher solute concentration and has lower water concentration (90/10)
● outside is greater than inside
Hypertonic
can cause an animal cell to shrink or shriveldue to water loss.
Hypertonic
● turgid
● flaccid
● plasmolyzed
Hypotonic, Isotonic, Hypertonic
It refers to the relative concentration of solutes in fluids separated by a selectively permeable membrane
Diffusion
It refers to a solution where water is drawn out of the cell.
Hypertonic
contains both the solute (solid) and a solvent which is usually a (liquid). A solute added in a solvent will naturally diffuse to form a solution.
Solution
involves the movement of molecules across the membrane but with the aid of either channel or carrier proteins. These molecules are usually those that cannot cross due to their molecular size or chemical nature
Facilitated diffusion
Oil is a (solute or solvent)
Solvent
● sit
● soaked
● transfer
