    About the Lecture

    The lecture G-protein Coupled Receptors – Second Messenger Systems by Georgina Cornwall, PhD is from the course Cellular Structure.


    Included Quiz Questions

    1. ...MAP kinase cascades for signal amplification
    2. ...molecular switches that connect pathways
    3. ...multiple cellular targets resulting in many cellular effects
    4. ...reduction in signal from reverse kinase cascades
    1. ...are the proteins that are activated by the G-protein to make the second messenger
    2. ... could be adenylyl cyclase or Phospholipase C
    3. ...could be cyclic AMP and PKA
    1. …adenylyl cyclase
    2. …guanylyl cyclase
    3. …phosphokinas
    4. …protein phosphatase
    5. …protein diphosphatase
    1. The DAG and IP3 are the signal-carrying molecules which bind to the cell membrane receptor during muscle contractions
    2. The phosphatidylinositol-4,5-bisphosphate (PIP-2) is a membrane phospholipid embedded in the inner leaflet of the cell membrane
    3. Diacylglycerol and inositol-1,4,5-triphosphate (IP3) act as second messengers in downstream signaling pathways
    4. Phospholipase C enzyme acts as an effector protein and hydrolyzes the PIP-2 to stimulate the muscle cell contractions
    5. The IP3 and DAG molecules stimulate the downstream signaling pathways to facilitate the release of hormones in the endocrine cells
