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?

- Model 4: Active Transport Area of detail ion binding site ATP binding site ATP ADP 26. Which part of the cell membrane is shown in more detail in Model 4?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. Scenario #3 Semi-permeable membrane Охудen Carbon Dioxide Lungs I Blood stream After studying the image above, select the statement(s) that would explain what is likely to happen. 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_forwardQuantitative – 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_forward

- blood flow - Oxygen molecules (O2) move from the lungs into the bloodstream, while carbon dioxide (CO2) molecules move from the bloodstream to the lungs (see Figure 3-2). Use these terms: diffusion, higher, hypertonic, hypotonic, lower alveolus (100 units O2) Movement of O, and CO, across the membrane occurs by CO2 O2 In this figure, O, is moving from the to the because the concentration of O, in the alveolus is while that in the capillary is capillary (40 units O2) FIGURE 3-2 Movement of oxygen molecules.arrow_forwardFor each of the following scenarios please describe which part of the cell theory is supported by this evidence. Options: • • • Cells come from preexisting cells, cells are the basic unit of life, all living things are made of cells 1. A botanist (plant scientists) named Schlieden studied a large variety of plant cells under the microscope and found that all plants were made of cells. Option 1 2. A scientist named Leeuwenhoek found that after studying a wide variety of organisms the smallest living organism he observed was made of only one cell. Option 1 3. A scientist named Virchow viewed cells under a microscope and found that cells would grow and split into new cells. Option 1 4. A zoologist (animal scientist) looked at a large amount of different animal tissues under a microscope and found that all animals are made of cells. Option 1 5. Robert Hooke studied cork and many other substances and found that they contained little square boxes he called cells. Option 1arrow_forwardyou discover that myoglobin has an isoelectric point of 6.8 and chymotrypsin has an isoelectric point of 8.75 after performing the technique called isoelectric focusing which of the following proteins would you expect to find closer to the negative electrode - myoglobin - chymotripsin - equal migration - not enough info - iso focusing separate proteins based on cell size not isoelectric pointarrow_forward

Based on your results, would it be more efficient for a multicellular animal to grow by increasing the size of cells or by increasing the number of cells? Explain your answer referencing your results from the lab. Only students in Science 10 need to complete the following question. 3. The concept of surface area to volume ratio can be applied to multicellular organisms. Using your understanding of the surface area to volume ratio, explain why moving from the equator towards the North Pole, bears (Sun bear, Panda bear, Black bear, Grizzly bear, and Polar bear) increase in size.
