AIPMT PRELIMS 2000 Chemistry Chlorophyll and its Components MCQ Question

Type: MCQ-fact-Easy-Class 12

Mg is present in :

A

Chlorophyll

B

Haemoglobin

C

Vitamin12Vitamin^{-12}

D

Vitamin-B

Correct Answer

Option A

Detailed Explanation

Magnesium (Mg) is an essential element found in chlorophyll, which is the green pigment in plants responsible for photosynthesis. It plays a crucial role in the process by helping to capture light energy. On the other hand, haemoglobin primarily contains iron (Fe) as its central atom for oxygen transport in the blood, and it does not contain magnesium. Vitamin B encompasses a group of vitamins, none of which specifically require magnesium for their structure. Vitamin -12 (which is likely a typo for Vitamin B12) also does not contain magnesium. Therefore, the only correct option is (1) Chlorophyll, which contains magnesium. Thus, the correct answer is A.
