| COMMENT |
Chlorophyll is the principal photoreceptor in photosynthesis, the light-driven process in which carbon dioxide is fixed to yield carbohydrates and oxygen. Chlorophyll is a cyclic tetrapyrolle, similar in structure to the heme group of globins (hemoglobin, myoglobin) and cytochromes. Chlorophyll differs from heme in a few major respects, most notably that the central metal ion in chlorophyll is magnesium while that in heme is iron. |
