There are two types of photosystems: photosystem I (PSI) and photosystem II (PSII). Both photosystems contain many pigments that help collect light energy, as well as a special pair of …

And then they actually go to photosystem I and they get hit by another photon. Well, that's a simplification, but that's how you can think of it. Enter another high energy state, then they go …

In photosystem I, there's another chlorophyll a pair called P700, and that's because it optimally absorbs light of a wavelength of 700 nano-meters. And you have something similar that …

As it turns out, the atoms of carbon in your body were once part of carbon dioxide (CO 2 ) molecules in the air. Carbon atoms end up in you, and in other life forms, thanks to the second …

Es gibt zwei Arten von Photosystemen: Photosystem I (PSI) und Photosystem II (PSII). Beide Photosysteme enthalten viele Pigmente, die dabei helfen, Lichtenergie zu sammeln, sowie ein …

As photosystem II (PSII) absorbs energy from light, electrons are excited to a higher energy level and accepted by ADP to form ATP. C As photosystem II (PSII) absorbs energy from light, …

All photosynthetic plants, algae, and cyanobacteria contain chlorophyll a, whereas only plants and green algae contain chlorophyll b, along with a few types of cyanobacteria 2, 3 .

Estas bacterias utilizan el sulfuro de hidrógeno ( H 2 S ‍ ) como fuente de electrones y producen azufre elemental como subproducto. Además, las bacterias púrpuras del azufre tienen un …
