Answer:
inactive proteins can be activated by phosphorylation
Explanation:
Proteins are regulated after translation by the non-covalent binding of small molecules. These molecules include amino acids or nucleotides. A change in the conformation and thus, the activity of the protein is usually achieved when this occurs.
Proteins could also be regulated by phosphorylation which is the addition of phosphate groups of specific amino acids on the protein.

Answer:
The pH of a solution containing 0.1 mM H+ is 4
Explanation:
The pH of any solution is given by the following mathematical equation -
![pH = -log[H_{+}]\\](https://tex.z-dn.net/?f=pH%20%3D%20-log%5BH_%7B%2B%7D%5D%5C%5C)
----------- Equation (A)
Where,
= the concentration of hydrogen ion in the solution.
Given
= 
Substituting the given value in equation (A) , we get -
![pH = -log[10^{-4}]](https://tex.z-dn.net/?f=pH%20%3D%20-log%5B10%5E%7B-4%7D%5D)
Hence, The pH of a solution containing 0.1 mM H+ is 4
