Chapter 6: Membrane |
CELLS/Cell membrane/Diffusion/screen 5
If you heated the liquid in the animation would you expect the time to reach equilibrium, an even distribution of the dye molecules, to increase or decrease? Why?
GENETICS/Cell Division/Meiosis/screen 8
How long would it take the demonstration in the animation to reach complete equilibrium?
If you placed the same concentration of lactose (milk sugar) molecules on the left side of the membrane as you have in sucrose molecules on the right, and they are both too big to pass through the membrane, what would happen?
CELLS/Cell membrane/Osmosis/screen 3
If you placed the same concentration of lactose (milk sugar) molecules on the left side of the membrane as you have in sucrose molecules on the right, and they are both too big to pass through the membrane, what would happen?
CELLS/Cell Membrane/Active Transport/screen 2
Phosphorous is needed for cell metabolism. If sufficient ATP was present, could the sodium-potassium pump conduct the phosphorous against a concentration gradient?
CELLS/Cell Membrane/Exo/endocytosis/screen 1
If a polar molecule too large to pass through a lipid bilayer is synthesized in the endoplasmic reticulum of a cell how could it get outside the cell without passing through the plasma membrane?
