Question

31. The total solute concentration in a red blood cell is about 2%. Sucrose cannot pass through the
membrane, but water and urea can. Osmosis would cause such a cell to shrink the most when the
cell is immersed in which of the following
1) a hypertonic sucrose solution
2) a hypotonic sucrose solution
3) a hypertonic urea solution
4) a hypotonic urea solution
32 What process does link reception of cell signals to responses within the cell?
1) a signal transduction pathway
2) protein synthesis by ribosomes
3) budding of transport vesicles from the Golgi
4) active transport of the signal into the cell
33 If an animal cell is placed into a solution whose concentration of dissolved substances is higher
than that inside the cell
1) the cell will swell
2) the cell will shrivel
3) the solution is described as hypertonic 4) both 2and 3are correct
34 Which of the following processes does cause substances to move across membranes without the
expenditure of cellular energy?
1) Endocytosis 2) Exocytosis 3) Active transport 4) Diffusios
