Statement I : The activity of an enzyme is pH-dependent.
Statement II : A change in pH, affects the solubility of the enzyme in water.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) –Both statement I and statement II are correct
Almost all enzymes are proteins. There are some nucleic acids that behave like enzymes. These are called ribozymes. One can depict an enzyme by a line diagram. An enzyme like any protein has a primary structure, i.e., the amino acid sequence of the protein. An enzyme like any protein has a secondary and tertiary structure.
The activity of an enzyme is pH dependent because, with a change in pH, the enzymes are denatured. Change in pH also affects the solubility of enzyme in water.
