Set 6 – Lab 6: Diffusion, Osmosis, and Cell Membranes You watched a video about dialysis and how solutions can diffuse across a membrane. A solution consisting of a 10% glucose and 10% starch were used to fill dialysis tubing. The tubing was tied and sealed and placed into a beaker of deionized water (DI water).  Part 1:  Based on the initial concentrations of water inside and outside the dialysis tubing, what can you conclude about the direction of osmosis? Explain (2 pts) Part 2: The majority of one substance remained in the tubing, while there were slight traces left of the other substance that mainly diffused into the beaker. The majority of what substance remained in the bag? (1 pt.) __________ Part 3:  Which reagent supported your argument for a positive result of the substance in a higher amount that remained in the bag in Part 2?   (1 pt) ____________  

Set 9 – Lab 7: Enzymes Fill in the blanks of the reaction equation from Lab 7.  Blank #1 = Which substance was used as the reactant? Blank #2 = Which substance was used for the enzyme? Blank #3 = Which substance(s) were the result creating a final product or products? Blank #4 Extra Credit (+1): Was this reaction exergonic or endergonic? 

QUIZ PROBLEM #6 Instructions:  Choose the ONE best answer below. There is no need to write anything on your “work” pages.   Question: When characterizing atoms using the quantum-mechanical model, there are four quantum numbers.  Which one of the following best describes the information they each provide?
