Question

Catalase Enzyme Activity. The food items soaked in vinegar showed a positive reaction because the vinegar, which is an acid, broke down the hydrogen peroxide into water and oxygen

True or false?

Answer 1

Answer =

False :

Explanation = The food items soaked in vinegar showed a positive reaction because the vinegar, which is an acid, broke down the hydrogen peroxide into water and oxygen. this statement is false because:

Catalase catalyzes the decomposition of hydrogen peroxide to water and oxygen.

acid that is vinegar does not catalyzes the decomposition of hydrogen peroxide to water and oxygen. in this case ,food items soaked into vinegar, the food items contains the catalase enzyme. the food items like as vegatables are rich source of catalase.

In this case, a positive reaction is due to presence of catalase in food items , not due to vinegar.if there is reaction between vinegar and hydrogen peroxide there is formation of paracetic acid.
