chlorophyll
Chlorophyll or chlorophyll is a key molecule in photosynthesis, a pigment that acts as an antenna to absorb light energy. There are various kinds of chlorophyll, such as chlorophyll a, chlorophyll b, chlorophyll c, chlorophyll d, chlorophyll e and bacteriol chlorophyll a and b. It contains magnesium ions in the center of the porphyrin ring, and about 200 chlorophyll are gathered to transfer energy to one reaction center chlorophyll. Chlorophyll a is contained in all plants that have photosynthesis. On the other hand, chlorophyll b is contained in terrestrial plants, green algae or euglena, and some algae have chlorophyll c or chlorophyll d. Other red-colored bacteria that have photosynthesis have bacterial chlorophyll. Chlorophyll in higher plants contains chlorophyll a and chlorophyll b in a ratio of about 3: 1. Among these, it is chlorophyll a that directly transfers the light energy to the chemical reaction system, and the light energy absorbed by the other pigment is once transferred to the chlorophyll a and then moved to the chemical reaction system.
