BCH4024 11724 OC F24 E3 Q13: A novel organism has been found with a unique electron transfer chain. The Eo values for the individual components are as follows: Component A = + 1.004 mv Component B = -0.027 mv Component C = +0.321 mv Component D = -0.064 mv Component E = -0.457 mv What is the likely order of the transfer of electrons in this chain?

BCH4024 11724 OC F24 E3 Q30: When energy status in the liver cell is low, AMP-activated protein kinase (AMPK) is activated. One of the targets of AMPK is HMG-CoA reductase. Which of the following is a TRUE statement?

BCH4024 11724 OC F24 E3 Q48: You see a patient in your clinic who is severely sick and reveals that they have eaten a meal that contained fermented coconut. You remember from your biochemistry days that a toxin, bongkrekic acid (structure below), is produced by a contaminating bacterium in fermented coconut and corn. This toxin specifically inhibits adenine nucleotide translocase. What process is most directly affected by this toxin?

BCH4024 11724 OC F24 E3 Q1: You see a patient in your clinic who complains that they are unable to carry out long, intensive exercise. You have a muscle biopsy performed, and the results indicate a deficiency in the enzyme that catalyzes the following reaction. What is the enzyme, and why does a deficiency of this enzyme lead to rapid muscle fatigue?
