This is a diffusion topic: During the time the simulation ran, did the concentration of either the oxygen molecules or the carbon dioxide molecules ever reach a state of equilibrium inside and outside of the cell? Why or why not? If equilibrium was reached, how long did it last? Explain why.

If the oxygen level were to suddenly drop to near 0, initially how would you expect the cell to react (aka what would happen to the cell/what would the cell do in order to stay alive and functioning)?  The cell would:

Diatomic oxygen (O2) exhibits which of the following membrane transport movements? A. it is not able to cross the membrane by passive transport, because it is big, polar, and inorganic it is not able to cross the membrane by active transport, because it is big, polar, and inorganic it is able to cross the membrane by facilitated diffusion, because it is small, polar, and organic it is able to cross the membrane by active transport, because it is big, nonpolar, and organic it is able cross the membrane by simple diffusion, because it is small, nonpolar, and inorganic

SIDE A SIDE B 5 g Glucose 0g Sucrose 100 mL Water jinarnitoij - 0.20M 0g Glucose 5 g Sucrose 100 mL Water Linannitol) 0.20 M Side A Side B How would you describe the level of water (the membrane is permeable to glucose but not permeable to sucrose) in this experiment after 5 days? Multiple Choice water level will be higher on side B water level will stay the same on both sides water level will be higher on side A water level will decrease on both sides

Suppose that initially there are 100 Nat and 25 K+ ions inside the cell, near the sodium-potassium pump. After how many cycles is the number of Na ions the same as the number of Kions inside the cell? With the initial values for each type of ion provided above, how many ions of each type are in the cell? What is the total number of ions at this time? Show your work and explain.

You design a new matrix to regenerate skin during skin graft. The matrix have cells that need nutrients, such as glucose. You need to figure out the diffusion profile of glucose into the matrix. Assuming glucose has a radius of 1.0nm, you are interested in diffusion from the blood vessels into the matrix, which are 1cm away. The blood viscosity is 3cP, and the glucose concentration in the blood is 4mM. What is the initial flux of glucose? (use 1.38 * 10^-23 J/K for Boltzmann's constant).

b) If you soak an animal cell that is permeable to both water and glucose in either 5.5% glucose or 0.9% NaCl (both isosmotic solutions), the cell exposed to 5.5% glucose will gain water, while the cell exposed to 0.9% NaCl will not gain water. Predict why this is the case.

So when a cell is in electrochemical equilibrium I know for Cl there is no net movemnet because the electrical and concentration gradients have an equal effect. I also know that when K is an electrochemical equilibrium that the concentration effect is bigger than the electrical effect. Which effect is greater for Na when it is in electrochemical equilibrium the electrical or concentration gradient??

You treat cells with 2,4 dinitrophenol (DNP). This compound creates a temporary channel in the inner membrane of the mitochondria though the protons can move. Which of the following would you observe in these cells? Select all that apply The cells do not synthesize ATP in the presence of DNP The cells synthesize ATP in the presence of DNP The cells reduce oxygen in the presence of DNP The cells generate carbon dioxide in the presence of DNP

Describe the basic process of aerobic cell respiration,  what molecules are needed to begin the process of each major step and what are the products of each major step, and where in the cell does each major step take place?
