Answer #1

IP3 binds and opens the Ca2+ channels on the endoplasmic reticulum.

IP3 is produced by the action of phospholipase C on the phosphatidylinositol 4,5 bisphosphate, it is found in the membrane the diacylglycerol and IP3 produced by the action of phospholipase C on phosphatidylinositol 4,5 bisphosphate, IP3 moves through the cytosol to the endoplasmic reticulum.

cAMP is produced by adenyl cyclase.

G proteins like Ras, Raf etc are found inside the cells.

so the answers are

a) IP3 binds Ca channels on the endoplasmic reticulum.

b) IP3 moves through cytosol.

e) G proteins are found on the inside of the cells.

    1. You are interested in how cyclic-AMP-dependent protein kinase A (PKA) functions to affect learning and memory, and you decide to study its function in the brain. It is known that, in the cells you are studying, PKA works via a signal transduction pathway like the one depicted in Figure 16-15. Furthermore, it is also known that activated PKA phosphorylates the transcriptional regulator called Nerd that then activates transcription of the gene Brainy. Which, if any of the situations described...

    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....
