Title: How can molecules and/or ions be transported across the membranes of animal cells? Post by: mjcurry on Feb 22, 2016 Osmoregulation must be tightly controlled in order to keep ion concentrations at their appropriate levels.
This is true for all types of cells, regardless of whether they are prokaryotes or eukaryotes. a. How can molecules and/or ions be transported across the membranes of animal cells? Briefly explain each mechanism of transport. b. You are a physician and your patient has come into the hospital slightly dehydrated. You prescribe 0.9% saline, given intravenously (directly into the bloodstream). This concentration of saline is isotonic to normal blood composition. Explain why you might choose to give your patient isotonic saline. c.
