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.

Chloramphenicol binds in the active site of the large ribosomal subunit and inhibits peptidyl transferase activity in the 23s rr
valentina_108 [34]
This inhibition is restricted to bacterial translation because; the peptidyl transferase is an enzyme aminoacyltransferase as well as the primary enzymatic function of the ribosome, which forms peptide bonds between adjacent amino acids using tRNAs during the process of translation. Therefore, inhibition of this enzyme means that the process oof translation wont take place, hence proteins will not be formed and thus the bacteria will die.
