Unformatted text preview: BMJ 300 Exam 1 February 13,2008 32. In one form of Cushing's disease the adrenal cortex produces excessive amounts of glucocorticoids. In these individuals you would expect levels of Adrenocorticotropic Hormone (ACTH) and levels of Corticotropin Releasing Hormone (CRH). (9) low, low $ th i g h , high c. high, low d. low, high 33. The function of the thyroid gland is to generate a hormone essential for normal metabolism by adding to . a. phosphate groups, serine b. phosphate groups, tyrosine (^iodine, tyrosine a. methyl groups, cholesterol e. iodine, serine 34. The binding of a hormone to a transmembrane protein receptor can affect: f vesicle exocytosis enzyme activation. c. vesicle endocytosis d. gene transcription and translation. _^ (fiS^All of the above may be affected. 35. In the endocrine system, hormones are secreted in one region and have their effects on other cells. Which of the following is most important for determining the function of the hormone? a. The proximity of the target cell to the site of hormone secretion. b. The endocrine organ that secretes the hormone. (c^The availability of a receptor specific for the hormone. d. The lipid solubility of the hormone. e. The degree of phosphorylation of the hormone. 36. In the accompanying figure, the hormone receptor complex will act as a(n) ((^tyrosine kinase. Qpy GTP binding protein. c. serine/theronine kinase. d. phosphatase.-^ e. transcription factor. 37. In the accompanying diagram, the hormone would most likely be a: @ peptide or protein b. steroid hormone c. derivatve of cholesterol d. soluble in water and c are correct Hormone Receptor Hormone Plasma Membrane BMS 300 Exam 1 February 13, 2008 20. The living epithelial cells in the skin are the: ,a: keratir ocytes in the stratum corneum. fr melanocytes in the dermis. jg. fibrocytes in the dermis. (cpkeratinocytes in the stratum basale. e. a and d are correct 21. Proteins such as collagen and elastin that characterize connective tissue are: a. released from the cell by exocytosis before assembling into much larger proteins in the extracellular space. /K transmsmbrane proteins. c. components of the cytoskeleton d. synthesized on rough endoplasmic reticulum.

The linear sequence of amino acids in a protein is the: (ja)primar/ structure of the protein. b. secondary structure of the protein. c. tertiary structure of the protein. d. alpha helix. e. beta pleated sheet. 23. The sequence of bases TAG in DNA would lead to base pairing with an anticodon that has the sequence of: a. ATC b.AUC (g)UAG d.UTC e. none of the above 24.
