Unformatted text preview: e-mail Key A Quiz 6a 10/26/05 1. (4 pts) Draw the fatty acid represented as C10:2( ∆ 3,5 ). Show all atoms . 2. (7 pts) Below, ATP is abbreviated to show only the triphosphate explicitly. Write the hydrolysis rxn , drawing the products in the same level of detail as the A-P-P-P shown. Then list 3 reasons why ATP hydrolysis is so favorable. PRINT CLEARLY. Reasons hydrolysis is favorable: i. Pi resonance ii. decrease electrostatic repulsion iii. better product solvation iv. favorable H+ release 3. (8 pts) Match the molecule on the left with the description on the right. Write the letter in the blank. Use each letter, A – H once. F diacylglycerol A. weakly bound protein B glycosaminoglycan B. polymer with many negative charges G GPI C. oxidation level of an aldehyde H phospholipase A2 D. glucose fuel storage polymer A extrinsic protein E. linked exclusively β (1 → 4) C hemiacetal F. product of a phospholipase D glycogen G. anchors certain membrane proteins E cellulose H. a fatty acid is one product 4.
