Magnesium is present in which of the following__________________?
Correct answer: C. Chlorophyll
- A. Cytochromes
- B. ATP
- C. Chlorophyll
- D. Haemoglobin
Explanation
Magnesium is the central mineral ion in the chlorophyll molecule and is essential for capturing light energy during photosynthesis. Haemoglobin contains iron, while cytochromes contain iron and ATP contains phosphate groups, so students may choose haemoglobin by confusing the central metal ions of chlorophyll and haemoglobin.
