The Claim
Glucagon increases the phosphorylation of a specific set of 11 to 12 cytosolic proteins in hepatocytes by markedly enhancing cyclic AMP-dependent protein kinase activity, while angiotensin II and vasopressin have no effect on cyclic AMP levels in hepatocytes.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Glucagon triggers the addition of phosphate groups to 11 to 12 specific proteins inside liver cells by activating an enzyme that responds to cyclic AMP. Angiotensin II and vasopressin do not change cyclic AMP levels in these cells.
See the scientific wording
Glucagon increases phosphorylation of the same set of 11 to 12 cytosolic proteins in hepatocytes through a marked increase in cyclic AMP-dependent protein kinase activity, whereas angiotensin II and vasopressin do not alter cyclic AMP levels.
Glucagon binds to liver cells and triggers a chain reaction that raises cAMP levels, which turns on a specific enzyme that adds phosphate groups to 11 to 12 key proteins. These phosphorylated proteins then switch liver metabolism to break down glycogen and release glucose. Angiotensin II and vasopressin also phosphorylate the same proteins, but they use calcium instead of cAMP to activate a different enzyme that does the same job.
What the research says
1 studyGlucagon tells liver cells to release sugar by using a chemical called cAMP, while angiotensin II and vasopressin use calcium instead — the study proved this by showing each hormone changes the same liver enzymes, but through different signals.
