- G-protein Inactivation
- cAMP
Quiz zum Vortrag
Which actions occur in turning off the glycogen breakdown hormonal regulation pathway?
- cAMP is broken down by phosphodiesterase.
- Arrestin favors exocytosis.
- Caffeine inhibits glycogen phosphorylase.
- The α-subunit of the G-protein turns itself off.
- Phosphoprotein phosphatase converts GTP to GDP.
What masks the β-adrenergic receptor?
- The arrestin protein after phosphorylation on its intracellular part by G-protein receptor kinase enzyme.
- The G-protein receptor kinase, under the guidance of arrestin protein.
- The phosphate group on its extracellular domain part.
- The cAMP molecule on its intracellular domain sites.
- The GDP-αβγ molecular entity under the guidance of G-protein.
What does the alpha subunit of the G-protein do?
- It breaks down GTP.
- It synthesizes ATP.
- It breaks down GDP.
- It digests adenylate cyclase.
- It autodigests itself.
Which enzyme breaks down the cyclic AMP molecule?
- Phosphodiesterase
- G-protein receptor kinase enzyme
- Phosphatase
- Protein kinase A
- Phosphorylase kinase

Thank you so much This video helped me so much en my sesions of study
Thank you Dr. Ahern for this very comprehensive lecture. Going through the biochem book makes this topic very complicated. It is amazing how you can simplify this topic to get to the point and what we actually need to understand.
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
