Marvelous Membrane Members
Membrane protiens with carbohydrates attached that help cells identify one another
Glycoprotiens
When a cell is placed in an isotonic solution, the concentration of solute outside the cell is _________________ the concentration inside the cell.
The same as
Ion pumps use energy to move ions against the concentration gradient (low to high). This is an example of ________
Active transport
Hangover start who can oft be found between two ferns
Zach
Integrated proteins span the cell membrane, and because of this often have many _________ amino acids on their surface
non-polar
When a cell is placed in an hypotonic solution, the concentration of solute outside the cell is _________________ the concentration inside the cell.
less than
any transport that uses no energy and naturally trends towards equilibrium.
Passive transport
Canadian hoop star virally known as maple jordan
Barrett
Protein that could be used to help charged ions move across the membrane from high to low concentration
Chanel Protein
When a cell is placed in an hypertonic solution, the concentration of solute outside the cell is _________________ the concentration inside the cell.
larger than
CO2 can cross cell membranes using simple diffusion. This is because CO2 molecules are ________ and _______
Small and non-polar
Academy award winning actress known for her roles in My Cousin Vinny and the recent spiderman movies
Marisa
Cholesterol is this type of macro molecule (be specific)
and helps this type of membrane transport occur
steroid lipid
simple diffusion
A cell with a concentration of 7% salt is exposed to a 12% salt solution. What kind of solution to this, and what will the net movement of water in this situation be, and what will happen to the cell. Assume that salt cannot cross the membrane.
Hypertonic, water moves out, cell will shrink
Simple diffusion and facilitated are similar in that the move molecules in this direction.
They are also different in these 2 ways
High to low
Facilitated uses protein help, moves large or phobic molecules
The time of Harry Potters birth
Summer
Type of protein that often have many positively charged amino acids on their outer surface
Membrane Associate Protein
A cell with a concentration of 12% salt is exposed to a 7% salt solution. What kind of solution to this, and what will the net movement of water in this situation be, and what will happen to the cell? Assume that salt cannot cross the membrane.
Hypotonic, water moves in, cell swells.
Charged ions move across the membrane from low to high, then back across from high to low. Name any and all types of transport occurring here, and any and all proteins involved.
Active via ion pump, facilitated diffusion via channel protein.
