Question

Which of the following organelle(s) is/are site(s) for beta oxidation in plants?

• A. Chloroplast
• B. Mitochondrial matrix
• C. Peroxisomes
• D. Both b and c

Answer 1

The correct option is D Both b and c

Beta oxidation is the catabolic process by which fatty acids are degraded to acetyl CoA and energy rich molecules such as $FAD{H}_2$ and NADH are released. The acetyl CoA generated enters into the citric acid cycle. Whereas $FAD{H}_2$ and NADH are used in the electron transport chain. Beta oxidation occurs in the mitochondrial matrix of plants. Beta oxidation also occurs in peroxisomes when fatty acid chains are too long to be handled by mitochondria.

Chloroplast is the cell organelle where photosynthesis takes place in green plants.
