BMS 300 exam 1 (Correctly Solved)

which of the following would move from the nucleus into the cytoplasm through nuclear pores correct answers small and large ribosomal subunits Biphosphate is a drug commonly used to slow bone loss during the progression of osteoporosis. This drug affects the chemistry of bone by inhibiting the breakdown of hydroxyapatite to Ca2+ and PO4^2- ions. The cell type whose function you would expect to be inhibited by this drug would be the correct answers osteoclast the delivery of vesicles to the cytoplasmic side of the plasma membrane is thought to be carried out by the plus end directed motor protein, _____, which moves vesicles along filaments polymerized from _____ correct answers kinesin, actin when sugars are initially added to proteins in eukaryotes, they are covalently linked to a nitrogen in the R group of the amino acid asparagine. From what you know about protein glycosylation, you would expect this enzymatic reaction to occur in the correct answers endoplasmic reticulum In some forms of Addison's disease, the adrenal cortex (the target gland) releases far lower than normal amounts of cortisol. You would expect levels of corticotropin releasing hormone (CRH) released from the hypothalamus and adrenocorticotropic hormone (ACTH), released from the anterior pituitary to be _____ and _____ respectively correct answers low, low If you discover that the Kd for the concentration of hormone binding to its receptor is 10^-10 M, you would conclude that the receptor has a _____ affinity for the hormone so that a _____ concentration of hormone would effectively bind to the receptor correct answers high, low RNAase is an enzyme commonly found on the skin that helps protect against RNA viruses by breaking (hydrolyzing) covalent bonds in RNA molecules. You would expect this enzyme to break correct answers phosphodiester bonds between adjacent ribose molecules Integrins are transmembrane proteins that can bind to molecules called catenins which are cytoplasmic proteins and to laminins, which are extracellular protein. You would expect to find these transmembrane proteins in correct answers hemidesmosomes in epithelial cells in eukaryotes, enzymes that catalyze phosphodiester bond formation between adjacent 5-carbon sugars function in the correct answers nucleus Based on what you know of the probable origins of mitochondria in cells, you would expect the DNA in these organelles to be correct answers circular Which of the following would be expected to bind to the intracellular region of the receptor in a signal peptide/GTP complex correct answers the alpha subunit of the GTP binding protein
