Unformatted text preview: Key to example Midterm 1 Yeast maintain the concentration of sucrose (a sugar) inside their cells at a steady level, marked here by the dotted line. When cells of yeast are placed in media containing different sucrose con- centration, they transport it into the cell at the rate (sucrose/sec) indicated in the graph below. P and M define experimental ranges of sugar concentration outside the cell. 1. In the M concentration range sugar is taken up into the cell because of: a. diffusion b. unsaturated lipid chains c. formation of vesicles d. active transport e. plasmodesmata 2. In the P concentration range sugar is taken up into the cell because of: a. diffusion b. unsaturated lipid chains c. formation of vesicles d. active transport e. plasmodesmata 3. Given the properties of sucrose, the following is expected: a. sucrose will permeate through the lipid bilayer in both ranges b. a membrane protein will be involved only in range P c. a membrane protein will be involved only in range M d. membrane protein(s) will be involved in both ranges e. membrane lipid composition will change in the two ranges- 1 - 4. Which atomic bond is expected to have a biased distribution of the electrons involved: bond a C-H b C-C c H-H d O-H e O-O 5. Which molecular pair is expected to form a H bond?: molecule I molecule II a R-C=O H3C-R b R-CH2-NH2 H3C-R c R-CH=CH2 HO-CH2-R d R-CH=CH2 H3C-R e R-C=O HO-CH2-R 6. The above cell is most likely that of a _________ because of ______ a. prokaryote, membrane invagination b. prokaryote, lack of flagella c. eukaryote, lack of flagella d. eukaryote, many organelles e. prokaryote, nucloid 4. Which atomic bond is expected to have a biased distribution of the electrons involved: bond a C-H b C-C c H-H d O-H e O-O 5. Which molecular pair is expected to form a H bond?:5....
