Membrane Physiology Homework
1. You have a beaker filled with a solution containing 2M glucose, 4M urea and IM salt.
Suspended in the solution is a cell that containing a solution of IM glucose, 8M urea and 3M
salt. The membrane of the cell is permeable to glucose and salt but not urea. Answer each of the
following questions:
a. Where will water move?
b. Where will urea move?
c. Where will glucose move?
d. Where will salt move?
e. What will happen to the volume of fluid inside the cell?
f. What will happen to the osmolarity of the fluid inside the cell?

Which part of the cell membrane is shown in more detail in Model 4?arrow_forwardThis is not graded.arrow_forwardThe movement of molecules in and out of a cell is essential to its function. The cell membrane regulates this movement though processes such as diffusion, osmosis, active transport, etc. These activities on the next couple pages are designed to assess your understanding of these processes.

Choose ALL that apply. O The carbon dioxide molecules will move into the lungs until equalibrium is reached. O All the carbon dioxide molecules will move into the lungs to be exhaled. O All the oxygen molecules will move from the lungs into the blood stream. O The semipermeable membrane will prevent the movement of either molecule. O The oxygen molecules will move into the blood stream until equalibrium is reached.arrow_forward
- Quantitative – diffusion time: Consider a spherical, single-celled organism which needs oxygen tosurvive. a. Assume oxygen needs to diffuse from the outside of the cell to its center. Write an equation thatgives the diffusion time in terms of the cell radius. b. The cell has a 4 micron (m) diameter, and diffusion coefficient of oxygen is 1.8 x 10-5 cm2/s inwater (assume diffusion is the same through the cell membrane). How long does it take for oxygento diffuse to the center of the cell? c. Cells typically need key molecules such as oxygen to survive. Diffusion times of oxygen can limithow big cells can become. If the cell gets too large for oxygen to reach its center, the cell coulddie. Calculate the size of a cell at which oxygen diffusion time becomes too slow and so limits theability of the cell to get that big. Explain your assumptions. How does this compare to typical cellsizes?arrow_forwardMacmillan Learning Write equations for the hydrolysis of ATP and ADP.

Adenosine triphosphate, ATP, has one more inorganic phosphate group than does adenosine diphosphate, ADP. ADP has two phosphate groups, whereas adenosine monophosphate, AMP, has one.
