Answer #1

Answer : The right option is B

Exaplanation : When an hormone (ligand) binds to the receptors on the target cells, intially activation of G protein occurs which in turn activates mambrane bound enzyme called adenylate cyclase. This enzymes catalyses the reaction that results in the formation of Cyclic adenosine monophosphate (cAMP). cAMP activates Protein kinase A. Protein kinase A phosphaorylate key regulatory enzymes and proteins in the cells.

    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...
