    #Signal #transduction is the process by which an extracellular signaling molecule activates a membrane receptor that in turn alters intracellular molecules creating a response. Transmembrane receptors span the cell membrane, with part of the receptor outside and part inside the cell. The chemical signal binds to the outer portion of the receptor, changing its shape and conveying another signal inside the cell. Some chemical messengers, such as testosterone, can pass through the cell membrane, and bind directly to receptors in the cytoplasm or nucleus. Sometimes there is a cascade of signals within the cell. With each step of the cascade, the signal can be amplified, so a small signal can result in a large response.Eventually, the signal creates a change in the cell, either in the expression of the DNA in the nucleus or in the activity of enzymes in the cytoplasm.

    Phosphorylation is not synonymous with increased activity. In fact there are enzymes that are activated by dephosphorylation and inactivated by phosphorylation. Insulin in general dephosphorylates the enzymes it acts upon (despite initial tyrosine phosphorylation activity, it ultimately dephosphorylates and inactivates the target enzyme).
    For example, insulin stimulates glycogen synthase activity by dephosphorylating it. Check it out on wikipedia
    Keep it up !!!

    when the protein is phosphorylated by the TK, does the energy that was stored in the bond of the P in ATP go into the bond between the Protein and P? Is this why it's exciting, because potential energy is being passed from the ATP to the
    Protein-P, leaving the lesser potential energy ADP? Now the protein is energized, it can do more than just change shape and facilitate, it can do that and do work?

    Sugarplum, you are amazing.....! thanks...have an exam later on tonight...So is it safe to say, In theory and very simplified, a simple bone fracture will trigger neurons to release hormones into the blood stream to reach the fracture site and bind to healthy osteoblasts and trigger transduction leading to bone cell division:}...? sorry for my lack of jargon, first year here....lol
