Which cell organelle oxidise maximum type of respiratory substrates :-

Options

A. Mitochondria
B. Lysosome
C. Peroxisome
D. Chloroplast

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which cell organelle oxidizes the maximum types of respiratory substrates. This involves identifying the organelle responsible for energy production through the oxidation of various substrates.

2. **Identifying the Organelles**: The options provided are likely to include Mitochondria, Lysosomes, Peroxisomes, and Chloroplasts. We need to analyze each organelle's function in relation to respiration.

3. **Analyzing Mitochondria**: Mitochondria are known as the "powerhouse of the cell." They play a crucial role in cellular respiration, where they oxidize various substrates such as glucose, pyruvate, and fatty acids to produce ATP (adenosine triphosphate). This makes mitochondria the primary site for the oxidation of respiratory substrates.

4. **Examining Lysosomes**: Lysosomes are often referred to as "suicidal bags" because they contain digestive enzymes that break down waste materials and cellular debris. They do not play a role in the oxidation of respiratory substrates.

5. **Considering Peroxisomes**: Peroxisomes are microbodies that contain enzymes for breaking down fatty acids and detoxifying harmful substances. While they are involved in some metabolic processes, they do not oxidize as many types of respiratory substrates as mitochondria.

6. **Looking at Chloroplasts**: Chloroplasts are involved in photosynthesis, where they convert light energy into chemical energy. They do not participate in the oxidation of respiratory substrates.

7. **Conclusion**: After analyzing the functions of each organelle, it is clear that mitochondria oxidize the maximum types of respiratory substrates. Therefore, the correct answer is **Mitochondria**.

**Final Answer**: Mitochondria oxidize the maximum types of respiratory substrates.
