BCH4024 F25 E2 Q19: Which molecule acts as a second messenger in the phosphoinositide pathway activated by PLC? 

BCH4024 F25 E2 Q39: Estrogen binding to the estrogen nuclear hormone receptor stimulates cells to proliferate (grow and divide). Tamoxifen is a drug that was developed to treat breast cancer. It acts by binding the estrogen nuclear hormone receptor as an antagonist. How does tamoxifen alter gene expression in breast cancer cells?

BCH4024 F25 E2 Q37:  A novel organism has been found with a unique electron transfer chain. The Eo values for the individual components are as follows: Component A = -0.457mv Component B = -0.064 mv Component C = +0.321 mv Component D = -0.027 mv Component E =  + 1.004 mv What is the likely order of the transfer of electrons in this chain?

BCH4024 F25 E2 Q13: A 62-year-old female comes to your office for her annual physical exam. She reports that she feels healthy. However, you note that over the past 10 years she has gained 40-lbs. Her fasting blood glucose level is 195 mg/dL (normal is less than100 mg/dL). Her Hb1Ac is 9%. She states that she rarely exercises and eats a high fat diet. You diagnose her with insulin resistance, which results in cells not responding well to insulin signaling.  Which of the following would most likely be observed in this patient?

BCH4024 F25 E2 Q48: A patient is suffering from a metabolic disorder in which his glucokinase affinity for glucose and capacity is similar to that of his normal hexokinase. What effect would this disorder likely have on blood glucose levels? 

BCH4024 F25 E2 Q32: From the list provided below, which molecule would NOT be involved in the regulation of glycogen phosphorylase activity in muscle cells?

BCH4024 F25 E2 Q12: The protozoan, Plasmodium falciparum is the causative agent of malaria. This organism has become resistant to many drugs previously used to combat the disease. Resistance to treatment has developed because of overexpression of an ABC transporter by the protozoan. Which biological process is directly targeted by the overexpressed ABC transporters in Plasmodium falciparum to confer resistance?

BCH4024 F25 E2 Q28: Conversion of metabolically important hepatic enzymes from the non-phosphorylated form to their phosphorylated form:

BCH4024 F25 E2 Q46: What molecule is NOT a precursor of gluconeogenesis?

BCH4024 F25 E2 Q36: Elevated levels of calcium lead to the direct activation of the following enzymes, EXCEPT:
