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.
Answer:
Option b. Lowering the pH to kill pathogenic bacteria is correct answer.
Explanation:
bacterial motors are sensitive to pH. By decreasing the pH bacterial motors stops working. This was identified in a new research. But, with the weak acids and a lower internal pH they slow and ultimately stop moving (became dead).

<h2>Answer:</h2>
False
<h2>Explanation:</h2>
Human beings are not able to store protein. The human body can break down its muscle tissue to get certain amino acids, but it does not has specialized cells to store protein efficiently unlike it does fat and carbohydrate. For this reason, eating protein regularly is of great importance.
I found the exercise on the internet and attached are the descriptions.
Actin filaments:
-"play a role in cleavage furrow formation during cell division"
-"function in muscle contraction"
Microtubles:
-"make up the core of cilia and flagella"
-"are composed of tubulin subunits
-"maintain cell shape by resisting compression"
Intermediate filaments:
-"are not involved in cell motility"
-"fix certain organelles in place"
