Question

Out of peroxisomes, lysosomes and mitochondria, single membrane covering occurs in

• A. Both peroxisomes and lysosomes
• B. Only peroxisomes
• C. All of the above
• D. None of the above

Answer 1

The correct option is A Both peroxisomes and lysosomes

• A lysosome is a single membrane-bound organelle which contains digestive enzymes that digest excess or worn out organelles, food particles, engulfed viruses or bacteria and macromolecules.
• The peroxisome is a single membrane-bound organelle which contains oxidative enzymes and is responsible for lipid production and oxidation reactions within the cell.
• Whereas, mitochondria is a double membrane-bound organelle and is known as the powerhouse of the cell which is present in all eukaryotic cells.
• So, the correct answer is 'Both peroxisomes and lysosomes'.
