- In which direction (into or out of the cell) will water flow incells of Escherichia coli (an organism found in your largeintestine) suddenly suspended in a solution of 20% NaCl?What if the cells were suspended in distilled water? If growthnutrients were added to each cell suspension, which (ifeither) would support growth, and why?Consider three groups of solutes: (i) steroid hormones, fatty acids,and other lipids; (ii) inorganic ions; and (iii) polar organic solutessuch as glucose and amino acids. What is the principal mechanismby which each group crosses cell membranes passively? Why domembers of the first group cross in a fundamentally different wayfrom solutes belonging to the other two groups?Both H+ and Ca2+ are ions that move through thecytosol. Why is the movement of H+ ions so much fasterthan that of Ca2+ ions? How do you suppose the speed ofthese two ions would be affected by freezing the solution?Would you expect them to move faster or slower? Explainyour answer.
- Osmosis Define osmosis and why does blood cell become clear in distilled water?Ammonia (NH3) is a weak base that under acidic conditions becomes protonated to the ammonium ion in the following reaction: NH3 + H+ → NH+4 NH3 freely permeates biological membranes, including those of lysosomes. The lysosome is a subcellular organelle with a pH of about 4.5–5.0; the pH of cytoplasm is about 7.0. What is the effect on the pH of the fluid content of lyso- somes when cells are exposed to ammonia? Note: Ammo- nium (NH4+) does not diffuse freely across membranes.Ms. Sassa, a biology professor, wanted to demonstrate to her students the applicability of a dialyzing membrane (DM) as a model for the cell membrane by enclosing an aqueous solution in a DM bag and immersing in a beaker containing a different solution. Substances available which are permeable to the DM include 0.02 M NaCl, 0.03 M glucose, and 0.01 M glucose. The only substance available which is completely impermeable to the DM is the 0.01 M lactose. Using the substances given and materials such as a beaker, stirring rod, and string, draw ONLY ONE set-up that can be demonstrated by Ms. Sassa that will satisfy ALL of the following conditions: a. No solute will exhibit a net diffusion out of the cell. b. Glucose will exhibit a net diffusion into the cell. c. NaCl will exhibit a zero net movement. d. No net movement of lactose from the inside to outside of the cell. Make sure to label properly the substance inside the beaker and inside the DM bag.
- In medical industry, Medical devices use adhesives as one example of application of Intermolecular Forces of Attraction. Adhesives are used extensively in th medical world, from simple plasters to advanced medical applications. Adhesives are integral to the production of paper tissues and nappies, allow tablets to be protected from the effects of moisture and allow wounds to be dressed. Trans dermal patches, such as nicotine patch, permit a controlled delivery of nicotine into the bloodstream to help smokers quit. What are other line of work that applies the Intermolecular forces of Attraction. At least one example and its use in the certain field of work.The average concentration of salt in seawater is about 3.5 percent and the average concen- tration of salt in the human cellular environment is about 0.9 percent. Drinking seawater can be fatally harmful and is highly discouraged even in the most severe cases of dehydration. Which of the following provides the most likely cause for this fact? A B с D The increase in salt concentration in the extracellular environment will increase the per- meability of the cell membrane. The increase in salt concentration in the extracellular environment will cause the move- ment of water into the cell. The increase in salt concentration in the extracellular environment will cause the move- ment of water out of the cell. The increase in salt concentration in the extracellular environment will decrease the per- meability of the cell membrane.Some cells lining tubules in the kidneymaintain normal cell volume bysynthesizing organic solutes. Where inthe kidney would you expect to findthese cells? Explain.
