Question

Unique to lysosomes in comparison to peroxisomes is that

• A. Peroxisomes lack lytic enzymes.
• B. Lysosomal membranes show latency which peroxisome lack.
• C. Peroxisomes cannot be found in animal tissue.
• D. All of the above

Answer 1

The correct option is A Peroxisomes lack lytic enzymes.

Peroxisomes are microbodies which have enzymes for peroxide biosynthesis. They include peroxide producing enzymes like peroxidase, urate oxidase, amino acid oxidase and peroxide destroying enzyme catalase. Lysosomes are small vesicles containing hydrolysing enzymes and surrounded by single membrane. They are formed by Golgi apparatus and contain some 60 different types of hydrolytic enzymes eg nucleases, proteases, lipases, phosphatases etc. for digestion of various materials.
