the transport of substances through a cell membrane along a concentration gradient with the aid of carrier proteins. The ideas that all living things are composed of cells come from other cells defines: Central dogma. Water moves into root cells of a plant by... Q. Cell Transport Quiz. 10. Both processes of Passive and Active Transport involve the movement of molecules into and out of cells. What are the three components of a phospholipid? Cell membranes and transport quiz. This picture represents what type of cell transport? the difference in the concentration of molecules across a distance. The transport of materials across the cell membrane is known as cell transport; this can either be done through passive or active transport. 1. Which of these is part of the cell membrane? What two things are "needed" in primary active transport? describes a solution whose solute concentration is higher than the solute concentration inside the cell. Only letting certain molecules in/out of the cell, the process in which different molecules enter/leave a cell. evenly spread out). Why do the fatty acid tails face inwards? Prokaryotic cells do not have a nucleus and eukaryotic cells do. the pressure that is exerted on the inside of cell walls and that is caused by the movement of water into the cell. exocytosis. 2. Molecules move from LOW concentration to HIGH concentration. 1. Key molecules that pass through the membrane by facilitated diffusion, protein channels that allow for the transport of water, Glucose transporters (facilitated diffusion), protein channels that allow for the transport of glucose, protein that must bind to a receptor in order to open glucose transporters, protein channels that allow for the transport of specific ions, Water-loving (goes hand in hand with polar), Water-fearing (goes hand in hand with nonpolar). Cell Transport Vocabulary. Quiz & Worksheet Goals Students will be tested on the following topics in this quiz: a. isotonic b. hypotonic c. hypertonic d. none of the above _____ 2. membrane fuses with a vesicle to release molecules from a cell, In _ organisms individual cells must be able to "talk" with one another to maintain _, Maintaining internal balance, "not dying", A ligand bind to a receptor on the cell membrane OR inside the cell, A signaling molecule (ex. Cell Transport To keep cells functioning normally cells need to move particles in and out of the cell. a cell that ingests and destroys(digests) foreign matter or microoraganisms. It is a thick solution that fills each cell and is enclosed by the cell membrane. Certain things can enter while others cannot. Cell Transport Unit Test ~Please DO NOT write on the test~ I CAN describe the parts of cells. Increases at a slower rate. What direction does water move in osmosis? Cells use one of two processes, passive or active transport to move particles across a membrane. Hypertonic cell shrinks cell shrinks away from the cell wall Isotonic cell remains the same size cell remains the same size Hypotonic cell swells & bursts cell swells against the cell wall Matching – Match each term to its definition. Quiz on Cell Membrane (Plasma Membrane) Answers: 1.a) passive diffusion through the lipid bilayer 2. b)Active transport of ions 3. b)Na + K + ATPase 4. c)K + 5. c)Is important for maintaining a constant cell volume 6. c)-60 mV 7. d)Is used to deliver material into the extracellular space 8. b)Retrieve elements of the cell membrane after exocytosis C insoluble in water. What is the major function of the cell membrane? •Solute – The substance that dissolves to form a solution •Solvent – The substance in which a solute dissolves •Solution – A mixture of one or more solutes dissolved in a solvent.
