OSMOSIS
Osmosis is the simple diffusion of which molecule?
What is water?
True/false:
The cell membrane is semi-permeable
What is true?
True or false: Simple diffusion, facilitated diffusion, and osmosis are types of passive transport
What is True?
Are bacteria considered eukaryotic or prokaryotic?
What is prokaryotic?
What is the name of our university's president?
Who is Tony Allen?
True or false: Water moves against its concentration gradient in osmosis
What is false?
Fill in the blank:
The cell membrane is made of a ______ bilayer
What is phospholipid?
In facilitated diffusion, what kind of molecule is needed to help molecules diffuse across the membrane?
What are carrier proteins, proteins or channels?
Which organelle is the site of protein synthesis?
What are the ribosomes?
What year was DSU founded?
What is 1891?
When a cell is in a hypotonic solution, there is a higher solute concentration inside the cell than outside. Will water leave or enter the cell?
What is enter?
Name at least one function of the cellular membrane
What is separation from the ECM and regulation of the movement of materials in and out of the cell?
True or false: In active transport, molecules move from an area of high concentration to a low concentration (with their concentration gradient). This is a process that does not require energy.
What is false?
Name at least 1 of the cell junctions we discussed in class
What is plasmodesmata, gap junctions, tight junctions or desmosomes?
What is the name of our school mascot?
Who is "Too Fly"?
Describe the movement of water in an isotonic solution.
What is it will move in and out of the cell?
Is the cell membrane hydrophobic, hydrophilic, or amphipathic (both)?
What is amphipathic?
Name at least two key factor that might impact the ability of a molecule to diffuse across a membrane WITHOUT the help of a carrier protein.
What are charge, polarity, size, and concentration gradient?
Which of the cell junctions is ONLY found in plants
What are the plasmodesmata?
True or false: There used to be a Starbucks in Tubman before it burned down.
What is false?
The name of the channel protein that helps water move across the membrane
What are aquaporins?
Name at least one molecule, other than phospholipids, that is embedded in the cell membrane
What are cholesterol, proteins and sugars?
The sodium/potassium pumps move Na and K AGAINST their concentration gradients. Will the sodium be pumped in or out of the cell? What about the potassium?
What is sodium out, potassium in?
Site of macromolecule digestion; recycling of warn out organelles
What are lysosomes?
There are little robots that used to roam around campus and deliver food. What were they called?
What are Kiwibots?
