Flashcards in Cellular Transport Deck (38)
What are the five types of cellular transport?
What are the types of passive transport?
What are the types of active transport?
Water nutrients and __________ need to get into our cells
Carbon dioxide and _______ need to get out
The difference in concentration of molecules across a space
Measure of solute concentration
Direction of movement
High --------> low
Transport across the cell membrane that does not require energy
Moves concentration gradient ________.
The movement of molecules from areas of higher concentration (solute) to areas of lower concentration (solute)
The way ________ and ________ get in/out of cells
Oxygen and carbon
When the commentary ok or a substance is the same throughout the space.
(Ex food coloring)
The random drifting of particles suspended in a fluid ( a liquid or a gas )
The process by which water diffuses across the cell membrane from an area of lower solute concentration to an area of higher solute concentration
Movement from HIGH ---> LOW water concentration
Low solute equals ____
(Osmosis)high solute equals _____
Pressure that water molecules exert against cell walls
Loss of turgid pressure.
( wilted plants )
Cells burst because of excess turgor pressure.
When the concentration of solute molecules outside the cell is lower than inside the cell
More water than what is being dissolved
Concentration of solute molecules is higher than water molecules
More solute equals less water
Water travels to ___
Concentrations are equal.
Water will diffuse into and out of the cell at equal rate.
-drying out process
-40 days to dry out
-salt put on top
-hypo to hyper
Movement of molecules that cannot diffuse rapidly without the assistance of carrier protein.
