Acylhomoserine lactones used in quorum sensing regulate their own synthesis by an autoinduction system.
Numerous bacteria use acyl homoserine lactones (acyl-HSLs), significant intercellular signaling molecules, to track the density of their population for quorum-sensing control of gene expression. The LuxI family of proteins produces the signals in question.
A lot of proteobacteria use quorum-sensing signals from acyl-homoserine lactones.
Cells create a baseline amount of signal at low population densities, and when enough signal has accumulated in the environment, it binds to its receptor and activates quorum-sensing-dependent genes.
Blood sugar regulation in a diabetic patient is done by
Injecting prescribed quantity of hormone insulin after definite time intervals.
Consuming prescribed amount of sugars.
Injecting glucagon to maintain blood sugar level if alpha cells of the pancreas are also non-functional.
Explanation:
The concentration of sugar in the blood is regulated by the hormone, insulin, produced in the pancreatic beta cells in normal person and injected from outside in a diabetic person.
When the concentration of glucose in the blood is high, the insulin signals the hepatocytes to express their glucose transporters to take up the excess glucose from blood and convert them to glycogen.
When concentration of sugar in the blood is low, another hormone called glucagon, released from the alpha cells of the pancreas, signals the liver to carry out glycogenolysis (breakdown of glycogen to glucose) and release the glucose into the blood. This would maintain the glucose level in the blood.
In a diabetic patient, usually the beta cells of the pancreas are affected but not the alpha cells, so the glycogenolysis can occur in the body spontaneously.
But excess injection of insulin should also be avoided as that can cause the blood sugar level to come down below normal.
I have the same question as well but I don't know the answer. The only thing I know is that I believe C. Metamorphosis is not correct. But I am not 100% sure.
P.S. I may not be correct but I think it could be A. lithification because 'lithos' means rock.
