ss. Which of ths foilowing is a funcaion of ell sembsane peancin? b. cell recognition c enzyme d. transport ?. all of the above 49. Which substance may enter a cell through the process of sim a oxygen b. cholesterol c. carbon dioxide d. water e. all of the above ple diffusiom? 50. Facilitated diffusion differs from simple diffusion in that a facilitated diffusion always reqaires ATP b. simple diffusion requires a concentration gradient c. facilitated diffusion requires an integral protein d. simple diffusion moves substances from low to high concentration e. simple diffusion always moves molecules that are not lipld solable 51. A solution is hypotonic to a cell if it contains a a higher solute concentration than the cell b. a higher water concentration than the cell c. the same water concentration as the cel d. the same solute concentration as the cell ne solute concentration as the cen 52. A human cell placed in a hypertonic solution will: a. lyse b. crenate c. lose much of its solute d. gain a very small amount of water e. remain unchanged 53. The sodium/potassium exchange pump uses what method of cellular transpont? a. primary active transport b. facilitated diffusion c.osmosis d. simple diffusion e. secondary active transportExplanation / Answer
48. e)all of above
they are all functions of proteins present on cell/plasma membrane
49. e)all of above
oxygen,water,carbon diaoxide passed freely through cell membrane.and as long as it concern with small cholesterol molecule they also passes through cell membrane freely which is by simple diffusion.
50. a)facillited diffusion always requires ATP.
facillited diffusion is active process which always requires energy. and simple diffusion is passive process which dont requires energy.
51. a)higher solute concentration of cell
hypotonic solution have lesser solute content and high water content as compare to other solution.
52. b)crenate
53. a)primary active transport
