Question

on the type of cell resulting in new gene e enters the nucleus and activates specifie a step in the regulated the coat b) dynamin binds to the cytosolic e) the adaptor proteins called Sec2seSarl to relea SNAREs 14. The ed assembly of the coat found on a CoPll vesicle is surface of the donor membrane that will form the vesicle d) a Sarl-GEF in the donor membrane ca e) specitie -SNARES in the donor mem that 15. T membrane proteins that receptors that allow animals to smell hundreds of different scents e) two inir N-terminalence followed by an internal start-transfer sequence c) two internal start-transfer sequences mortain seven transmembrane a-helices. The set of signal sequences the membrane must begin with the arrangement of an olfactory receptor in b) a cleaved N-terminal signal sequence followed by an ermal start-transfer sequence followed by an internal stop-trans ernal stop-transfer sequence followed by an internal start-transier 16. The Ras protein a) contains three subunits, α, β and γ b) is found in the cytosol in its inactive form c) is mutated in many human an cancers to an inactive, nonfunctional form of the Ras protein a GEF that causes Ras to exchange GDP for GTP d) is activ e) all of the above are true 17. After leaving the endoplasmie reticulum in a vesicle, a from the cell goes a) to an early endosome b) to a late endosome protein that will be secreted c) directly to the plasma membrane for secretion d) to a lysosome e) to the cis face of the Golgi apparatus

Answer 1

13. a) activate MAP (mitogen activated protein) kinase module containing three protein kinases.

Ras a protein is tethered to plasma membrane by causing it to bind GTP. Once acivated can do variety of things such as it activates the enzymatic cascade of MAP kinase, which results in potent change in the cell.
