- 20. Active transport of a substanceacross a membrane requires A A gradientB the expenditure of ATPCwaterD diffusionDoctor's order says: Infuse 3000 mL of TPN over 36 hours Calculate the hourly rate. Show the computation. Final answer to the nearest whole number3. Quantitative – diffusion rate: Humans rely on their lungs to supply oxygen to their bodies. Each lungis made up of over 300 million alveoli or air sacs that provide a total surface area of 75 m2 over whichoxygen can diffuse. However, the recent COVID pandemic has caused problems both during and afterinfection for oxygen delivery. a. During COVID, patients can get pneumonia, where the lungs can partially fill with fluid. Thiscauses coughing but also prevents that part of the lung from absorbing oxygen. If 35% of thealveoli were filled with fluid, how much of the lung area (in m2) would still be functioning? b. How would the oxygen diffusion rate for the pneumonia patient compare with that of a normalperson? Write out and solve for the diffusion rate ratio. c. Sometimes people with severe pneumonia are given an oxygen canula to augment their breathing.Normal oxygen concentrations in the lung are 100 mm Hg of O2 (this is the partial pressure whichis proportional to concentration as…
- 5. Intravenous solutions must be prepared, to that they are isotonic to red blood cells. A0.9% salt solution is isotonic to red blood cells. Keeping this in mind, explain whatwould happen to a red blood cell placed into a solution of 99.3% water and 0.7% salt.Note to obtain full marks you must care both the intercellular environment to theextracellular environment (solute vs solvent).If a fresh-water fish is placed in a seawater aquarium, then the fish may thrive because hemolysis will occur. thrive because seawater is isotonic with freshwater. die because crenation will occur. die because the cells will burst.Red blood cell(Nucleus, hemoglobin, biconcave, oxygen, transport) 1.
