Answer:
Trypsin cuts at lysine and arginine amino acid residues at the carboxyl end. Chymotrypsin cuts at tryosine , phenylalanine, and tryptophan amino acid residues at the carboxyl end.
Explanation:
Trypsin and chymotrypsin are known as proteolytic enzymes which are actively involved in the digestive system. They are both secreted by the pancreas and are majorly involved in the breakdown of protein in the small intestine.
Trypsin cuts at lysine and arginine amino acid residues at the carboxyl end. Chymotrypsin cuts at tryosine , phenylalanine, and tryptophan amino acid residues at the carboxyl end.
I believe the answer to this is Both
Answer:
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.
Crystalline silica is a natural compound in the earth's crust and is a basic component of sand and granite. Silicosis is an incurable disease of the lungs caused by breathing crystalline silica dust. This dust can cause scar tissue to form in the lungs.
