Cellular Transport Test Flashcards
What is Hypotonic?
There is a LOWER concentration of solute molecules OUTSIDE than inside the cell
What does Isotonic mean?
There is the SAME concentration of solute molecules outside the cell as inside
What is the pressure inside of a plant cell caused by water pushing against the cell wall called?
Osmotic pressure
The SWELLING and BURSTING of the cells when water enters is called…
Cytolysis
What type of solution makes the cells swell and burst?
Hypotonic
What does placing the cells in a hypotonic solution cause the osmotic pressure to do?
Increase
The SHRINKING of plant cells when water leave so the cell membrane pulls away from the wall is called what?
Pinocytosis
What type of soulmate on causes plasmolysis?
Hypertonic solution
What is the substance that dissolves to make a solution
Solute
Where do molecules move during diffusion?
Down the concentration gradient
When the concentration of a solid is the same throughout the system the system has reached….
Dynamic equilibrium
Osmosis
The diffusion of water across a selectively permeable membrane
Phagocytosis, pinocytosis, and exocytosis are all kinds of what transport
Active transport
Glucose enters cells most rapidly by…
Facilitated diffusion
Where does the energy for active transport come from?
Mitochondria
Which transport requires energy from ATP to move substances across the membrane?
Active
What does a cell use expend energy to transport substances?
Endocytosis
White butt blood cells engulf, digest, and destroy invading bacteria using what?
Phagocytosis
The carrier proteins that help in facilitated diffusion are what proteins?
Peripheral proteins
All of the following are kind of passive transport except
Phagocytosis
Endocytosis that brings in small dissolved molecules are and fluids is called…
Pinocytosis
What do Golgi bodies use to transport molecules out of cells
Exocytosis
What is the pressure exerted by water moving during osmosis?
Osmotic pressure
Placing an animal cell in a hypotonic solution will cause the water to do what?
Move into the cell
When molecules move down the concentration gradient it means they are moving from…
An area of high concentration to an area of lower concentration
Gas is like oxygen and carbon dioxide move across cell membrane using…
Diffusion
Which transport requires energy to move molecules across membranes
Active transport
What moves carbon dioxide molecules and oxygen molecules from a high concentration to a lower concentration across membranes
Diffusion
A small membrane sack used to transport substances to bring exocytosis and endocytosis is called
Vacuole
Pinocytosis, phagocytosis and sodium Potassium pumps are all kinds of what kind of transport
Active
What uses ATP to move the potassium ions out of a cell while he moves the two potassium ions in
A sodium – potassium pump
Proteins that stick into the cell membrane either Parkway or all the way through our called
Integral proteins
The shrinking of animal cells that are placed in a hypertonic solution is called
Phagocytosis
What does hypertonic mean?
That there is a GREATER concentration of solute molecules OUTSIDE than inside the cell
