Terms in this set (28)
Movement of particles or molecules from an area of high concentration to an area of low concentration
Diffusion of water across a selectively permeable membrane
Selectively pemeable membrane
A membrane that allows certain materials to pass through, but not others
A solution that has a higher concentration of solutes than another.
A solution that has a lower concentration of solutes than another.
Two solutions that have an equal concentration of solutes.
regulates and controls what enters or leaves the cell
Use of carrier PROTEINS for diffusion, does not require energy for a molecule to travel across the membrane
Moves molecules from high to low solute concentration
movement of molecules or ion into or out of the cell against its concentration gradient (from low to high) and requires an input of energy.
movement of substances into the cell by creating a new vacuole at the cell membrane. requires energy.
movement of substances out of a cell by merging a vacuole with the cell membrane. requires energy.
molecules move with the concentration gradient from high to low concentration NO energy required.
Types of Passive Transport
Diffusion, Osmosis and Facilitated Diffusion
Types of Active Transport
Endocytosis (phagocytosis and pinocytosis)
Exocytosis, and Protein Pumps - Lower Concentration to Higher Concentration
Cell membrane protein pump
These transport from low to high concentration
Requiring the expenditure of energy (ATP).
an embedded protein that helps a certain type of substance to cross the membrane
Result of diffusion where there is continuous movement of particles but no overall change in concentration because the concentration on the two sides is equal
Phospholipids, proteins, carbohydrates
Macromolecules in the cell membrane
Another name for the cell membrane
part of a phospholipid that is polar
part of a phospholipid that is nonpolar
transport materials into and out of cell, receive signal molecules
function of proteins in the membrane
A cell in a hypertonic solution will
cell in hypotonic solution
A cell in an isotonic solution will
stay the same
In osmosis, water always goes to the ________________ solution.
