Answer #1

Answer 1)
d. PI3K is a lipid kinase, where PI3 is the lipid, and K is for Kinase

Answer 2)
b. CaM Kinase. Ca2+/calmodulin-dependent protein kinase II (CaM kinase II or CaMKII) is regulated by the Ca2+
/calmodulin complex.

Answer 3)
c. Protein kinase B (PKB), also known as Akt, is a serine/threonine-specific protein kinase that binds to PIP3

Answer 4)
d. Phosphoinositide 3-kinases, also called phosphatidylinositol 3-kinases generate Phosphatidylinositol (3,4,5)-trisphosphate, abbreviated PIP₃

Answer 5)
c. Phospholipase C (a class of membrane-associated enzymes) cleaves PI (4, 5) P2

Activated protein kinase C (PKC) can lead to the modification of the membrane lipids in the vicinity of the active PKC. You have discovered the enzyme activated by PKC that mediates the lipid modification. You call the enzyme Rafty and demonstrate that activated PKC directly phosphorylates Rafty, activating it to modify the plasma membrane lipids in the vicinity of the cell where PKC is active. Explain how each of the following will affect the lipid modification: A. a Ca2+ channel...
