A chemical messenger uses a G-Protein-linked, cAMP pathway to transduce its signal, which eventually leads to the activation of enzyme X. Bob has a genetic defect which inhibits GTP hydrolysis in his cells. How would this affect activation of enzyme X?
Homework Answers
The g protein camp pathway depends on the slow hydrolysis of g protein to its subunit. Once g protein coupled receptor is stimulated by enzyme X (in the extracellular), the conformational change will lead to formation of Gs subunit (in the intracellular) to release in exchange of a GDP for GTP. If GTP will not hydrolyse then enzyme X will not be activated in Bob.

A chemical signal can have different effects in different tissues, depending on the receptor type to which autonomic neurotransmitters and hormones bind to. For this reason, it is important to specify the signal molecule and its receptor and subtype when describing the control of a tissue. Most smooth muscle neurotransmitters and hormones bind to G-protein linked receptors. The second messenger pathways then determine the muscle response: IP3 triggers contraction and cAMP promotes relaxation. What neurotransmitter and its GPCR triggers IP3...

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...

Question 10-12
10. During the mating process, yeast cells respond to pheromones secreted by other yeast cells. These pheromones bind GPCRs on the surface of the responding cell and lead to the activation of proteins inside the cell. When a wild-type yeast cell senses the pheromone, its physiology changes in preparation for mating: the cell stops growing until it finds a mating partner. If yeast cells do not undergo the appropriate response after sensing a pheromone, they are considered sterile....
