Problem set 3: Chapter 10: Hemoglobin pg 203-204: 1, 3-6, 8 Note: For #8, P. falciparum is a causative agent of malaria. In sickle-cell amemia, hemoglobin molecules in the T-state can polymerize, forming long fibers. This leads to the traditional “sickle” shape seen in red blood cells. Sickled red blood cells have a much shorter half life than normal red blood cells. Why are people with sickle cell anemia resistant to malarial infection? Chapter 11: Carbohydrates: Page 324-325 1, 4, 7, 9, 12. For #4, prove it – remember your math for solving two variables. For #7, see page 309 and don’t forget your organic chemistry!!! Chapter 15: Metabolism and Thermodynamics Pg 431-432 1, 3, 5, 7, 8, 9, 12, 13. For 3a, just calculate Δ G o’ . For #5, Δ G o’ hydrolysis of ATP to AMP is –45.6 kJ/mole. Δ G o’ hydrolysis of Acetyl CoA to acetate and CoASH (CoA) is –31.4 kJ/mole. Also the back of the book has the wrong answer for 5a. For #12, Δ G o’ hydrolysis of ATP to ADP is –30.5 kJ/mole.

Unformatted text preview: Also, try this: Youre a biochemist hired by NASA to study the results of a probe sent to Rhea, an earth sized planet several light years away. There is a large amount of excitement over Rhea as it contains several primitive life forms resembling plants that contain carbohydrates and proteins! It is currently hypothesized that these plants could provide a source of nutrients for any future manned missions to Rhea. The most recent plant data from the probe is listed below: Carbohydrates: Two disaccharides detected: -L-glucopyranose linked to -L-fructofuranose in an 1- 2 arrangement. -L-galactopyranose linked to -L-glucopyranose in an 1-4 arrangement. Protein amino acid composition: D-glycine 7.5% D-alanine 7.2% D-serine 5.7% More data in next transmission. Armed with this, you dash into your supervisors office!!! What have you learned from this latest dataset from the probe? Why is it important?...
