Final Jeopardy Fluid Mosaic Model

Final Jeopardy Model for the cell membrane based on the changing location & pattern of protein molecules in a fluid, phospholipid bilayer. Definition of the Fluid Mosaic Model

$200 Selectively permeable The cell membrane allows only what’s needed in/out of the cell. This is called…

$400 Phospholipid: The name of this molecule & its parts:

$600 Carbohydrate chain Glycoprotein Protein Name of this molecule & its parts:

$800 Glycolipid = carbohydrate attached to phospholipid Name this molecule & its parts

$1000 1. Channel proteins: move substances in/out freely 2. Carrier proteins: interacts with certain substances to move them in/out of cell 3. Cell Recognition: glycoproteins that identify the cell as “self” 4. Receptor Proteins: receive signals from surroundings 5. Enzymatic: biochemical reactions 5 membrane proteins & their functions

$200 Movement of substances down their concentration gradient & across the cell membrane Define passive transport

$400 Diffusion, osmosis, & facilitated transport Types of passive transport

$600 Diffusion is any substance; osmosis is only water molecules moving Osmosis crosses a membrane Difference between diffusion & osmosis

$800 Facilitated transport uses membrane proteins Difference between diffusion & facilitated transport

$1000 • Water • Small, non-polar molecules like oxygen & carbon dioxide • Lipid soluble molecules like alcohols Molecules that pass into/out of the cell passively.

$200 Active transport moves substances up their concentration gradient so requires energy Difference between passively & actively moving substances

$400 Active transport, exocytosis, & endocytosis Names of processes of actively moving molecules

$600 Pinocytosis (“cell drinking”) – endocytosis of small or liquid substances Phagocytosis (“cell eating”) – endocytosis of large substances Difference between pinocytosis and phagocytosis

$800 Ribosomes on ER make proteins; rough ER transports proteins to the Golgi; Golgi modifies & packages proteins in vesicles that fuse with the cell membrane releasing proteins out of the cell = exocytosis Relationship between ribosomes, rough ER, Golgi, & exocytosis

$1000 Explain the sodiumpotassium pump

$200 Tonicity = measure of osmotic pressure Solutions can be isotonic, hypertonic, & hypotonic Define tonicity & list 3 possible situations

$400 No net water movement, isotonic, no change to cell Net water movement? Type of solution? Affect on cell?

$600 More water into cell; hypotonic; cell swells Net water movement? Type of solution? Affect on cell?

$800 More water moves out of cell; hypertonic; cell shrinks Net water movement? Type of solution? Affect on cell?

$1000 Crenation – animal cell shrinks Plasmolysis – plant cell shrinks Turgid – plant cell swells Lysis – animal cell bursts Define: crenation, plasmolysis, turgid, lysis

$200 Hydrophobic = water-fearing Hydrophilic = water-loving Define hydrophobic & hydrophilic

$400 Phagocytosis – type of endocytosis When a white blood cell engulfs a pathogen, this type of transport is occurring.

$600 To provide energy ATP’s function

$800 Cell recognition proteins (glycoproteins) The type of transport protein that causes trouble with transplants

$1000 Nerve & muscle cells Where the sodium-potassium pump can be found.
