- Glyoxysomes
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of seed germination and organelle function.
Step 2: Detailed Explanation:
Glyoxysomes are specialized peroxisomes found in germinating seeds.
They contain enzymes of the glyoxylate cycle.
The glyoxylate cycle converts fatty acids to sugars (gluconeogenesis).
This is important in oilseed germination (e.g., castor, sunflower).
Dictyosomes (A): Golgi apparatus (protein processing).
Oleosomes (B): Lipid bodies (storage of oils).
Mitochondria (C): ATP production (respiration).
Thus, glyoxysomes convert fatty acids to sugars.
Step 3: Final Answer:
Thus, glyoxysomes contain enzymes for converting fatty acids to sugars, which corresponds to option (D).

- Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): The disruption of $\beta$-oxidation of fatty acids in plants can potentially reduce stress-induced ROS accumulation and improve its stress tolerance.
Reason (R): In plants, $\beta$-oxidation of fatty acids takes place predominantly in peroxisomes, where first enzyme of $\beta$-oxidation viz. fatty acyl CoA oxidase produces large amounts of hydrogen peroxide.
In light of the above statements, choose the correct answer from the options given below. - The serum level of which of the following metabolites can effectively distinguish "Vitamin B12 deficiency" from "Folate deficiency" ?
