Why Is Catalase in Potatoes

Catalase in general seems to protect organisms, including potato cells, from the effects of hydrogen peroxide. In plants, catalase is primarily located in peroxisomes, cell organelles which are like lysosomes, but break down simpler molecules.

Why does Potatoes have catalase?

Potatoes, particularly, contain high amounts of catalase, which is mysterious because plants do not filter toxins from food. Catalase is involved with photorespiration, however, which explains its presence, but does not account for its abundance.

Why does potato have less catalase than liver?

Larger particles decreased the rate of reaction because they require more energy to break down. The liver contains more of the enzyme catalase, which breaks down hydrogen peroxide. … The potato contains less of the enzyme catalase, therefore requires more activation energy, slowing down the rate of reaction.
