Which of the following sequences is correct?
| a. binding of a signaling molecule to its receptor → G protein activation → phospholipase C activation → IP3 production → increase in cytoplasmic calcium concentration |
| b. binding of a growth factor to its receptor → phosphorylation cascade → activation of transcription factor → transcription |
| c. diffusion of a signaling molecule across the plasma membrane → binding of the signaling molecule to its receptor → movement of the signaling molecule-receptor complex into the nucleus → transcription |
| d. binding of a signaling molecule to its receptor → G protein activation → adenylyl cyclase activation → cAMP production → protein phosphorylation |
| e. All of the choices are correct. |

Assume that the binding of one molecule of epinephrine to a seven-transmembrane helix (7TM) receptor (also called the G protein-coupled receptor, or GPCR) results in the activation of 480 Gα subunits. In addition, suppose that each activated adenylyl cyclase catalyzes the conversion of 40 ATP molecules to cAMP per second. (Assume that each G protein activates a single unique adenylyl cyclase.) Calculate the number of moles of cAMP that are produced per second. Enter your answer to at least two...

Drosopholia eye development is an example of cell differentiation directed by signal binding to a receptor tyrosine kinase (RTK). In this pathway, R7 photoreceptor development requires a receptor (SEV, sevenless), which is activated by binding to a plasma membrane bound signal (BOSS, bride-of-sevenless) displayed on the adjacent R8 cell Receptor activation leads to activation of RAS via two proteins, Drk (down- stream of receptor kinases) and Sos (son-of-sevenless). Activated RAS leads to activation of a phosphorylation cascade that activates the...

You are interested in cell size regulation and discover that signaling through a GPCR is important in controlling cell size in rat white blood cells. The G protein downstream of this receptor activates adenylyl cyclase, which ultimately leads to the activation of PKA. You find that cells that lack the GPCR are 15% smaller than normal cells, whereas cells that express a mutant, constitutively activated version of PKA are 15% larger than normal cells. Furthermore, the normal blood cells become...
