Question

Major function of peroxisomes is oxidation of

• A. Excess purine
• B. Surplus amino acids
• C. Alcohol and drugs
• D. All of the above

Answer 1

The correct option is D All of the above

• The peroxisome is a single membrane-bound organelle which contains oxidative enzymes and is responsible for lipid production and oxidation reactions within the cell.
  
• The important oxidation reactions of peroxisomes within a cell are-

1. Oxidation or breakdown of excess purines i.e, adenosines monophosphate and guanosine monophosphate to uric acid.
   
2. It contains the enzyme called D-amino acid oxidase which oxidises amino acids.
   
3. It also oxidises or metabolises alcohol and drugs in the liver by peroxisomal catalase.

• So, the correct answer is 'All of the above'.
