Question

Enzyme catalase is seen in:

• A. Lysosome
• B. Spherosome
• C. Peroxisome
• D. All of the above

Answer 1

The correct option is C

Peroxisome

The correct option is C:

Explanation of the correct option:

1. Peroxisomes are responsible for a number of oxidative reactions.
2. Enzyme catalase decomposes hydrogen peroxide into water and oxygen.
3. Thus, this enzyme protects the cell from oxidative damage.
4. So, it occurs in peroxisomes.

Explanation of the incorrect option(s):

Option A:

Lysosomes are rich in hydrolytic enzymes.

Option B:

Spherosomes contain hydrolytic enzymes as well and are also called plant lysosomes.

Final answer: Enzyme catalase is seen in Peroxisome.
