Discover how photosynthesis works, the role of chlorophyll, and why this natural process is essential for life on ...

Light-dependent reactions. When a photon of light hits the reaction center, a pigment molecule such as chlorophyll releases an electron. The released electron escapes through a series of protein ...

Discovered around half a century ago, the Fd/Trx pathway has long been credited with regulating many light dependent reactions in chloroplasts, the organ in the leaf where photosynthesis occurs.

Chemists develop a quantum dot system that uses 99% less energy to drive tough organic reactions, offering a leap forward in ...

Chemists at the School of Science of the Hong Kong University of Science and Technology (HKUST) have recently made ...

First, in the “ light-dependent reaction,” a chloroplast captures the energy from a photon, then uses it to split a water molecule into oxygen atoms and hydrogen ions. As already mentioned, the oxygen ...

Although this final stage doesn’t need light, it does need the products of the light-dependent reactions, which don’t last for very long inside plant cells. So photosynthesis really only ...

Up to now, it had been assumed that such a light-dependent reaction cannot occur in enzymes. "The enzyme we have identified belongs to a very large family of enzymes, ... is not light-dependent.
