Question Detail
Question
Consider the following statements: 1. Peroxisomes contain amino acid oxidases, urate oxidases and catalases. 2. In mitochondria, the Krebs-cycle reactions occur in the outer mitochondrial membrane. Which of the statements given above is/are correct?
Correct Answer
Option A is the correct answer.
Detailed Explanation
Statement 1 is correct: Peroxisomes contain oxidative enzymes such as amino acid oxidases, urate oxidases, and catalase, which breaks down hydrogen peroxide. Statement 2 is incorrect: Krebs-cycle reactions occur in the mitochondrial matrix, not in the outer mitochondrial membrane. The outer membrane is permeable to small molecules and contains porins, but is not the site of the Krebs cycle.
Hint
Recall the location of metabolic pathways and the enzyme content of organelles.
