A. Will only phosphorylate glycogen synthase (GS) after GS has been phosphorylated by casein kinase.
Explanation:
Glycogen synthase kinase (GSK) is a type of enzyme capable of phosphorylating serine and threonine residues on the glycogen synthase (GS). The insulin hormone activates the synthesis of glycogen by dephosphorylating GS, but it is a mechanism that depends on the previous phosphorylation of GS by Casein Kinase (CK). GSK is also known to phosphorylate the insulin receptor (IRS), and thus controlling glucose metabolism.
the molecules at the surface are being pulled by other molecules. The pulling forces the water to curve. ... The positive hydrogen ends of one water molecule attract the negative oxygen ends of nearby water molecule.
Because gametes are haploid cells they have half the number of chromosomes in a normal diploid cell. Therefore, the fly traps gamete cells will have 4 chromosomes.
