Which of the following is incorrectly matched?
Correct answer: E. Option E
- A. Option A
- B. Option B
- C. Option C
- D. Option D
- E. Option E
Explanation
The correct answer is Option E. The smooth endoplasmic reticulum (SER) is primarily involved in lipid synthesis and detoxification processes, but it does not directly produce Vitamin D. Instead, Vitamin D synthesis begins in the skin when 7-dehydrocholesterol is converted to previtamin D3 upon UV exposure. This previtamin D3 is then converted into active forms of Vitamin D through processes that involve the liver and kidneys, where the SER plays a role in further modifications but is not the initial site of Vitamin D production.Option A, Option B, Option C, and Option D are all correctly matched with their respective functions:Ribosomes are essential for protein synthesis.Lysosomes are involved in the breakdown of foreign particles.Centrioles assist in forming spindle fibers during cell division.Peroxisomes produce hydrogen peroxide as they metabolize fatty acids and detoxify various substances.
