Unformatted text preview: BIBC 102 Metabolic Biochemistry KEY Summer Session 2011 Homework 4 (40 pts.) 1) (8 pts.) An experiment is done to measure electron transport and ATP synthesis in isolated mitochondria. Sketch a plot of the hypothetical experimental results if you measure both O 2 consumption and ATP synthesis (y-axis; show each with a separate line) versus time. Start the experiment (t = 0) with succinate, ADP, and Pi in the mix and successively add an uncoupler of ATP synthesis and electron transport (at t = 4 min.) and then an inhibitor of ATP synthase (at t = 8 min.). Indicate the point that each agent is added. 2) (8 pts.) Give three possible fates of Acetyl-CoA. For each, give the general name of that metabolic pathway utilizing it, and what end product or payoff is for the cell. Also, state whether that fate/pathway for G6P would most likely occur under high blood glucose conditions, low blood glucose condition, or if that pathway is not dependent on blood glucose concentrations....
