Chlorophototrophic
WebMar 1, 2024 · Because high-intensity, short-wavelength electromagnetic radiation at Earth's surface would have been damaging for the first chlorophyll (Chl)-containing cells, photosynthesis probably arose at hydrothermal vents under low-intensity, long-wavelength geothermal light. The first photochemically active pigments were possibly Zn-tetrapyrroles. WebGreen bacteria are anoxygenic chlorophototrophic bacteria: they do not produce oxygen, they use light as their primary energy source for growth, and they use (bacterio)chlorophylls ( (B)Chls) for light capture and conversion into chemical energy (as adenosine triphosphate (ATP) and reducing power).
