1 of 18 1. A hormone receptor is found to recruit histone deacetylase complexes to its target genes in the absence of the hormone, and recruit protein complexes with histone acetyltransferase activity to mediate ligand-dependent transcriptional activation. Which of the following indicates whether this receptor interacts with cytoplasmic heat shock proteins (cHSPs) and/or with the retinoid X receptor (RXR)? In the absence of hormone: In the presence of hormone: A. Receptor interacts with cHSPs Receptor interacts with RXR. B. Receptor does not interact with cHSPs Receptor interacts with RXR. C. Receptor interacts with cHSPs Receptor does not interact with RXR. D. Receptor does not interact with cHSPs Receptor does not interact with RXR. Question 2 of 18 2. Which of the following characteristics contributes to the ability of glucokinase to function efficiently in liver cell glucose metabolism? A. Relatively low Vmax – lower than that of hexokinase. B. Km is greater than fasting blood glucose concentration. C. Inhibition by glucose-6-phosphate. D. Inhibition by insulin. Question 3 of 18 3. A 40-year old man is taking a medication that selectively inhibits the intestinal hydrolysis of (1->4) glycosidic bonds between two glucose molecules. This drug will most likely impair digestion of which of the following carbohydrates? A. Cellulose B. Galactose C. Lactose D. Maltose E. Sucrose Question 4 of 18 4. A 6-year old boy is diagnosed with a glycolytic enzyme deficiency. His hemoglobin affinity for oxygen is reduced as a result of accumulation of 2,3 bisphosphoglycerate (2,3-BPG) in his red
