Answer: adenylyl cyclase inositol triphosphate mainly known as IP3 causes the release of Calcium ions directly from the inracellular stores and causea contraction.
Explanation:
IP3, inositol phosphate is a second messenger a signaling molecule. It is made by hydrolysis of phosphatidylinositol 4,5-bisphosphate (PIP2), a phospholipid that is located in the plasma membrane, by an enzyme phospholipase C.
IP3 binds to the calcium channels and opens Ca2+ channels that are embedded in the ER membrane, releasing Ca2+ into the cytosol. Calcium ions released may cause contraction and regulate the Ca2+ channels in the membranes.
Answer:
Difference between fusion reaction and fission reaction.
Explanation:
Fission reaction produce energy while fusion reaction absorb energy.This happens because fission reaction deals with the breakdown of one larger nucleus which result in the generation or liberation of energy.Whereas Fusion reaction combines two smaller atomic nuclei,as a result of which it requires energy for the joining of two smaller atomic nuclei into a larger nucleus.
Answer:
Tree frogs use plants as protection. Golden jackals, once they have been expelled from a pack, will trail a tiger to feed on the remains of its kills. Goby fish live on other sea animals, changing color to blend in with the host, thus gaining protection from predators.
