Cell Transport Review Pick A Category Babyish 12345 Hardest 12345 Easy 12345 Evil 12345 Medium 12345 Don’t You Dare Do That! 12345 Hard 12345 Harder 12345 Babyish __________ is when water diffuses across a selectively permeable membrane. Category Osmosis Babyish What are the characteristics of an isotonic solution When the concentration of dissolved substances in the solution is the same as the concentration of dissolved substances inside the cell. Category Babyish Look at the illustration of an animal cell. What kind of solution does the illustration represent? a hypotonic solution Category Babyish When a cell used energy to transport a particle through its plasma membrane toward the side of higher concentration, the cell is using ______. active transport Category Babyish The diagrambelow shows what cell process? Exocytosis Category Easy Which of the following is NOT a type of passive transport? diffusion osmosis endocytosis facilitated diffusion endocytosis Category Easy Chamber A contains 40% helium and Chamber B contains 20% helium. Chambers are connected by a tube the molecules are free to cross. Which of the following will occur? - some helium will move from chamber A to chamber B - some helium will move from chamber B to chamber A - helium will remain concentrated in chamber A - all of the helium will move into chamber B Category some helium will move from chamber A to chamber B Easy Which of the following is a type of active transport? - sodium potassium pump - endocytosis - exocytosis - all of these all of these Category Easy Active transport requires: - a concentration gradient - osmosis - energy - a hypertonic solution energy Category Easy Diffusion and osmosis are processes in which particles move randomly across the plasma membrane. What type of movement are diffusion and osmosis? - endocytosis - exocytosis - active transport - passive transport passive transport Category 4. ?__________ is when water diffuses across a selectively permeable membrane. Medium What will happen to an animal cell placed in a salt water solution? - The cell will shrink - the cell will expand - the cell will burst - the cell will shrink and then expand and then shrink again The cell will shrink Category Medium cell's cytoplasmic volume increases when placed in an aqueous solution. The solution's osmolarity is said to be ___________ relative to the cell. - hypertonic - supersonic - gin and tonic - Isotonic - hypotonic hypotonic Category Medium An animal cell placed in a hypertonic solution will: - survive - take on water - lose water - divide - Change function lose water Category Medium If a cell has a solute concentration of 0.07% which of the solutions would be hypotonic to the cell? a. 0.01% solute b. 0.1% solute c. 1% solute d. 10% solute 0.01% solute Category Medium In an isotonic solution there would be: a. no net movement of water b. net movement of water into the cell c. net movement of water out of the cell d. bursting of the cell no net movement of water Category Hard Cells in a fish's gills pump out salt even though the salt water the fish lives in has a greater concentration of salts than the cells themselves do. What process do these cells use to remove the salt? a. b. c. d. active transport diffusion facilitated diffusion osmosis active transport Category Hard When neurotransmitters are secreted from nerve cells across a synaptic cleft from synaptic vesicles, this is an example of - osmoregulation - exocytosis - pinocytosis - endocytosis - phagocytosis exocytosis Category Hard Why do plant cells behave differently to animal cells when placed in a hypotonic solution? a. Plant cells are permeable to water b. Plant cells do not carry out active transport c. Plant cells contain a vacuole d. Plant cells have a cell wall . Plant cells have a cell wall Category Hard The sodium-potassium pump functions to pump -sodium ions into the cell and potassium ions out of the cell. - sodium and potassium ions into the cell. - sodium and potassium ions out of the cell. -sodium ions out of the cell and potassium ions into the cell. -sodium and potassium ions in both directions across the cell membrane. -sodium ions out of the cell and potassium ions into the cell. Category Hard What is the source of energy used to power the sodium-potassium pump? •breakdown of ATP •formation of ATP •transport of ATP by the pump • breakdown of GTP • transport of GTP by the pump •breakdown of ATP Category Harder ____________________ allows a cell to stockpile substances in far greater concentrations than they occur outside the cell. sodium-potassium pump Category Harder True/False Ion channels are usually able to transport only one type of ion. True Category Harder True/False Facilitated diffusion moves molecules and ions in one direction only, while active transport moves them in two directions. False Category Harder True/False Pinocytosis helps the cell rid itself of wastes. False Category Harder The process in which an amoeba engulfs its prey and takes it in is known as ____________________. Phagocytosis Category Hardest The sodium-potassium pump a. b. c. d. increases the concentration of sodium ions inside the cell. decreases the concentration of sodium ions inside the cell. increases the concentration of potassium ions inside the cell. both (b) and (c) D Category Hardest True/False , Correct the false statement Osmosis helps the cell rid itself of wastes. Exocytosis Category Hardest True/False , Correct the false statement The transport of specific particles through a membrane by carrier proteins up their concentration gradients is known as facilitated diffusion. sodium-potassium pump Category Hardest True/False , Correct the false statement When the concentration of solutes outside the cell is equal to the concentration of solutes inside the cell, the cell solution is hypotonic relative to its environment. isotonic Category Hardest True/False , Correct the false statement Diffusion is an active process that requires a cell to expend a great deal of energy. Sodium potassium pump Or Endocytosis/Exocytosis Category Evil Endocytosis is the process of a. b. c. d. moving large particles out of the cell. small particles out of the cell. large particles into the cell. small particles into the cell. c Category Evil How do fat-soluble molecules normally get into a cell? a. they dissolve in the fat layers of the membrane and enter the cell by diffusion b. they pass through protein pores in the cell membrane c. they are absorbed by phagocytosis d. they never get in A Category Evil When a cell bursts due to osmosis, it is in a solution that is: a. hypertonic b. isotonic c. hypotonic d. either A or C D Category Evil Which of these equations is correct? a. ATP + inorganic phosphate --> ADP b. ADP + inorganic phosphate --> ATP c. ATP + ADP --> inorganic phosphate B Category Evil Which of the following pieces of evidence would suggest that a substance entered a cell via active transport as opposed to passive transport? a. b. c. d. the substance moved across the membrane via a carrier protein the substance moved from a high concentration to a low concentration ATP was required for transport the substance moved across the membrane via a channel Category C Don’t You Dare Do That! The concentration of calcium in a cell is 0.3%. The concentration of calcium in the fluids surrounding the cell is 0.1%. How could the cell obtain more calcium? a. b. c. d. active transport diffusion osmosis facilitated diffusion A Category Don’t You Dare Do That!
