    About the Lecture

    The lecture β-adrenergic Receptor Signaling by Kevin Ahern, PhD is from the course Hormones and Signal Transduction. It contains the following chapters:

    • β-adrenergic Receptor Signaling
    • G-protein Inactivation
    • cAMP

    Included Quiz Questions

    1. cAMP is broken down by phosphodiesterase
    2. None of the answers are true
    3. Caffeine inhibits glycogen phosphorylase
    4. Arrestin favors exocytosis
    5. All of the answers are true
    1. The a-subunit of the G-protein turns itself off
    2. Phosphoprotein phosphatase converts GTP to GDP
    3. Turning off the breakdown pathway also turns off the synthesis pathway
    4. None of the answers are true
    5. All of the answers are true
    1. The arrestin protein after phosphorylation on its intracellular part by G-protein receptor kinase enzyme
    2. The G-protein receptor kinase under the guidance of arrestin protein
    3. The phosphate group on its extracellular domain part
    4. The cAMP molecule on its intracellular domain sites
    5. The GDP-αβγ molecular entity under the guidance of G-protein
    1. Its GTPase activity leads to the formation of GDP-α
    2. Its autocatalytic activity leads to the formation of GMP-α from the GDP-αβγ
    3. Its autocatalytic activity leads to the formation of GTP-α from the GTP-αβγ
    4. Its autocatalytic activity leads to the formation of GTP-α from the GMP-αβγ
    5. Its autocatalytic activity leads to the formation of GMP-α from the GMP-αβγ
    1. Phosphodiesterase
    2. G-protein receptor kinase enzyme
    3. Phosphatase
    4. Protein kinase A
    5. Phosphorylase kinase

    shallow lectures
    By gioia b. on 06. February 2018 for β-adrenergic Receptor Signaling

    the lectures is shallow; i think that more details are needed. it is ineffectual for the level required from the biochemestry course of the Med University of Florence. cordially gioia
