The activator of phosphatase enzyme is _.
Correct answer: B. Mg2+
- A. Mn2+
- B. Mg2+
- C. Zn2+
- D. None of these options are correct
Explanation
OPTION A: The activator of the phosphatase enzyme is not Mn2+ because it is not the right type of ion to activate the enzyme.OPTION B: The magnesium ion is a necessary cofactor of the phosphatase enzyme in humans. Some common cofactors are: Manganese is the cofactor for catalases, peroxidases, and superoxide dismutases. Chloride ion for salivary amylase.OPTION C: The activator of the phosphatase enzyme is not Zn2+ because it is commonly associated with the inhibition of phosphatases, not activation. OPTION D: This option is not the right one here.

About Enzymes as Biocatalysts
Enzymes are protein or RNA biocatalysts that lower activation energy without being consumed, and their active sites bind specific substrates. The topic covers the lock and key and induced fit models, effects of temperature, pH and substrate concentration, cofactors, enzyme specificity, and competitive versus non-competitive inhibition.
