which of the following changes in the plasma membrane of a salmon is most likely to occur as it migrates to a much colder region of the Pacific Ocean? HInt: the fluidity of the salmon's plasma membranes must remain relatively constant during its migration. The percentage of integral membrane proteins in the plasma membrane would increase The percentage of unsaturated fatty acid tails in plasma membrane phospholipids would increase The percentage of unsaturated fatty acid tails in plasma membrane phospholipids would decrease The percentage of peripheral membrane proteins in the plasma membrane would increase
How would increasing the amount of saturated phospholipid tails in the cell membrane affect the membranes flexibility? Explain your answer.
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.
In an experiment, a 0.001 (mole fraction) solution of polysaccharide in water is made and is placed in the compartment A. Compartment B is filled with pure water. The two compartments are separated by a porous semi-permeable membrane that allows the exchange of water molecules between the two compartments, but not that of the larger polysaccharide molecules. part 1: Show that the chemical potential of water in compartment A is lower than that in compartment B by 2.48 J/mol.
Which of the following complexes is not involved in pumping protons to the inter-membrane space? O Complex IV O Complex III O Complex II O Complex I
During diffusion, what happens when the concentration of solutes on both sides of the biological membrane is the same? A) The solutes will move across the biological membrane towards the inside of the cell. B The solutes will move across the biological membrane to the outside of the cell. © The solutes will stop moving across the biological membrane. D The solutes will continue to move across the biological membrane in both directions.
You have a beaker filled with a solution containing 2M glucose, 4M urea and 1M salt.Suspended in the solution is a cell that containing a solution of 1M glucose, 8M urea and 3Msalt. The membrane of the cell is permeable to glucose and salt but not urea. Answer each of thefollowing 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?
Is the solute potential of the cell increased or decreased by plasmolysis? Explain. Diffusion- Effect of concentration. Please discuss the data below.
Consider the artificial cell experiment below: Lactose = 2.0 M Ca+ = 0.4 M The ion channels in the membrane will allow Ca+ to pass freely, but nothing else. The starting conditions for the experiment are shown. Lactose = 0.1 M Ca+ = 3.0 M Rewrite the following statement to make it correct: "Eventually, there will be a net movement of water out of the cell because the inside of the cell is hypotonic compared to the environment."

The enzyme acid hydrolase is manufactured by white blood cells. It functions in the lysosome and kills bacteria and viruses that have infected white blood cells. Where is the primary structure of acid hydrolase completed? Question 5 options: Cytoplasm Rough endoplasmic reticulum Golgi apparatus Lysosome
Which statement best fits the following diagram? The purplish dots are sugar molecules and the blue areas are water molecules. On the left side the water molecwles have a concentration of 99.1% and on the right side the water molecules have concentration of 99.9%. 1) The level of fluid on the left will rise because water will move by osmosis through the membrane. 2) The level of the fluid on the left will fall as water moves to the right by osmosis. 3) The level of the water on the left will rise as a result of sugar molecules diffusing through the membrane. 4) The level of the water on the left will fall as sugar molecules diffuse through the membrane.
