AP Biology:  Cells Recovery Test

Short Answer

	1.	An artificial cell consisting of an aqueous solution enclosed in a selectively permeable membrane is immersed in a beaker containing a different solution. The membrane is permeable to water and to the simple sugars glucose and fructose but impermeable to the disaccharide sucrose.

(A) Draw solid arrows to indicate the net movement of solutes into and/or out of the cell.
(B) Is the solution outside the cell isotonic, hypotonic, or hypertonic?
(C) Draw a dashed arrow to show the net osmotic movement of water, if any.
(D) Will the artificial cell become more flaccid, more turgid, or stay the same?
(E) Eventually, will the two solutions have the same or different solute concentrations?

For the following questions, match the labeled component of the cell membrane (Figure 7.1) with its description.

	2.	peripheral protein

	3.	cholesterol-Match and give the function.

	4.	fiber of the extracellular matrix

	5.	microfilament of the cytoskeleton

	6.	glycolipid-Match and give the function.

	7.	Follow the path of a protein produced by a cell from the instructions in the nucleus to its release from the membrane.

	8.	For Photosynthesis and Respiration, write out the complete, balanced equations. For each, identify during which step the reactants are used and for what purpose. Also indicate during which step each of the products is produced.  Finally, indicate where in the cellular organelle(s) each part of the reaction takes place.

For respiration, how do the equation and steps involved change if anaerobic respiration is done instead of aerobic? How is what follows anearobic respiration different in plants and animals?  

Contrast the efficiency of aerobic and anaerobic respiration.
