CASE STUDY - MY DOG IS BROKEN - QUESTIONSNames of Partners (2): BradleyAssignment 1a)Review Email 1 and then write an email to Tess identifying the first messenger that starts the signal transduction in the smooth muscle cell, the likely second messenger, and finally the cellular response caused by the cell signaling cascade. A: First Messenger = NO (Nitrous Oxide)Second Messenger= cGMP & Ca2+Response is more muscular relaxationb)Explain why the arrows go from small to bigger. A: The reason for this is due to the fact that there are more reactions happening… Whether the receptor that starts the cell signaling pathway is in the plasma membrane, orintercellular. For the smaller to bigger, is due to the more reactions that will happen within this process… this is due to the more that is intaking the more movement of the arrows getting bigger. c)Also identify whether the receptor that starts the cell signaling pathway is in the plasma membrane or intracellular.
