Assume that the following genes are mutated and completely lose their functions. What happens to the blood glucose levels after the affected individuals eat a glucose rich meal? Please explain. a) The glycogen phosphorylase kinase gene
b) The glycogen synthase kinase 3 gene

One of the essential post-translational regulatory mechanisms, which can influence the stability, activity, or localization of a protein is phosphorylation.  

a) The phosphorylation of glycogen phosphorylase takes place by phosphorylase kinase. After phosphorylation, the glycogen phosphorylase gets stimulated and mediates the process of glycogenolysis. In case, if a mutation occurs in the phosphorylase kinase gene, the activation of glycogen phosphorylase cannot take place, and as consequence glycogenolysis will fail to take place.  

b) The phosphorylation of glycogen synthase takes place by protein kinase A, also known as glycogen synthase kinase 3. After phosphorylation, the glycogen synthase becomes inactive and thus fails to mediate the process of glycogen biosynthesis. In case, if a mutation takes place in the protein kinase gene, the glycogen synthase enzyme will remain active all the time, and as a consequence, the process of glycogen biosynthesis takes place spontaneously.  

i think it’s c but i might be wrong. if i am let me know! have a good rest of your day as well!

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added
