Biol 232 Human Physiology - Answers to questions Essay

Biol 232 Human Physiology - Answers to questions - Essay Example In this case, the concentration of solute inside the artificial cell is equal to the solute concentration outside; hence, there is no movement of Na+ and Cl- ions across the membrane. b. Assume the membrane is permeable to both solutes; does the concentration of NaCl affect the movement of glucose through the membrane? Explain your answer. No, the concentration of NaCl will not affect the diffusion of glucose across the membrane. Solutes diffuse through the permeable membrane due to the difference in concentration per kind of solute (Saladin, 2009). That is, Na+ and Cl- ions will move across the membrane if there is difference between the NaCl concentration inside and outside the artificial cell. In the same manner, glucose molecules will move across the permeable membrane due to concentration difference of glucose inside and outside the artificial cell. Since Na+ and Cl- ions are different from glucose molecules, the NaCl concentration will not affect the diffusion of glucose across the membrane. c. Assume the membrane is permeable to both solutes, will we detect osmotic pressure in the cell after 1 hour? Explain your answer. Yes, an osmotic pressure will likely be detected due to the different concentration of glucose inside and outside the artificial cell.
