Question

Microbody involved in the catabolism of long chain fatty acids and play important role in synthesis of phospholipids

• A. Glyoxysomes
• B. Peroxysomes
• C. Sphaerosomes
• D. Lysosomes

Hint:

Peroxisomes perform \(\beta\)-oxidation of very long chain fatty acids and participate in plasmalogen synthesis.

Answer 1

The Correct Option is B

Concept: Peroxisomes are small membrane-bound microbodies present in eukaryotic cells. They contain oxidative enzymes that participate in several metabolic pathways. One of their important functions is the oxidation of long-chain fatty acids.

Step 1: Understand fatty acid degradation. Very long chain fatty acids undergo \(\beta\)-oxidation in peroxisomes. This process shortens fatty acid chains before further metabolism.

Step 2: Understand phospholipid synthesis. Peroxisomes participate in the synthesis of plasmalogens. Plasmalogens are special phospholipids that form important components of cellular membranes.

Step 3: Examine other options. Glyoxysomes are specialized peroxisomes in plants involved in conversion of fats into carbohydrates. Sphaerosomes mainly store lipids. Lysosomes perform intracellular digestion. Therefore none of these satisfy both functions mentioned.

Step 4: Final conclusion. The microbody involved in fatty acid catabolism and phospholipid synthesis is: \[ \boxed{\text{Peroxisome}} \] Hence option (B) is correct.
