Question

The early bacteria synthesized chlorophyll from

• A. Iron porphyrin
• B. Magnesium porphyrin
• C. Sulphur porphyrin

The Correct Option is B

Early bacteria synthesized chlorophyll using magnesium porphyrin as the central metal ion in the chlorophyll molecule. This differs from the iron-based porphyrin used by some other organisms.
