Membrane Transport Jeopardy Jeopardy Template

The Cell Membrane	Passive Transport	Osmosis	Active Transport	Random
100 What word is used to describe the cell membrane, meaning that it only lets certain molecules through? Semipermeable	100 True or False: Passive transport does not require energy. True	100 Osmosis is the transport of what type of molecule? Water	100 True or False: Active transport does not require energy. False	200 The purpose of membrane transport is to maintain ______. Homeostasis
200 What is another name for the cell membrane? Fluid mosaic / phospholipid bilayer	200 Passive transport is the movement of molecules from ____ to ____ concentrations. HIGH to LOW	200 In osmosis, water molecules move from ____ to ____ concentrations of water. HIGH to LOW	200 Active transport is the movement of molecules from ____ to ____ concentrations. LOW to HIGH	300 In diffusion, do the molecules move with or against the concentration gradient? With
300 Name the 3 components of the cell membrane. Lipid + Protein + Carbohydrate	300 Which type of passive transport requires a protein channel? Facilitated diffusion	300 What is the name of the protein channel specific to water molecules? Aquaporin	300 In active transport, how do large molecules enter the cell? Via endocytosis	400 True or False: In an isotonic solution, there is no movement of molecules across the membrane. False
400 What 2 types of molecules can directly cross the cell membrane? Small and nonpolar molecules	400 What 2 types of molecules require a protein channel to cross the cell membrane? Large and polar molecules	400 Do water molecules always move towards the area of higher or lower solute concentration? Higher solute concentration	400 Describe what happens in exocytosis. A vesicle within the cell fuses with the cell membrane, releasing the molecules from within the vesicle out of the cell.	500 Define a concentration gradient. A difference in the concentration of a molecule between two areas or across a membrane
500 Describe the structure of a phospholipid molecule. Hydrophilic head + 2 hydrophobic tails	500 According to passive transport, if there is a higher concentration of oxygen inside the cell compared to outside, will the oxygen molecules move into or out of the cell? The oxygen molecules will move out of the cell	500 Define a hypertonic solution and the effect it has on a cell. A hypertonic solution has a higher solute concentration compared to a cell, causing the cell to shrink because it loses water to its surroundings.	500 According to active transport, if there is a higher concentration of sodium ions outside the cell compared to inside, will the sodium ions move into or out of the cell? The sodium ions will move out of the cell	600 What conditions would cause a cell to fill with water? Give both the type of solution and the relative water/solute concentrations on either side of the membrane. Hypotonic solution - lower solute concentration outside of the cell aka higher water concentration outside of the cell
