Photon photosynthèse
WebApr 26, 2024 · Die Photosynthese läuft in zwei aufeinanderfolgenden Schritten ab: den Lichtreaktionen und den sich daran anschließenden lichtunabhängigen Reaktionen. 1.1 Die Photosynthese benötigt Licht und einen Gasaustausch WebThe energy of the photon is used to excite an electron of a pigment. The free energy created is then used, via a chain of nearby electron acceptors, for a transfer of hydrogen atoms (as protons and electrons) from H 2 O or hydrogen sulfide towards carbon dioxide, eventually producing glucose.

WebDec 24, 2024 · The general equation for photosynthesis is therefore: 2n CO2 + 2n DH2 + photons → 2 (CH 2 O)n + 2n DO Carbon dioxide + electron donor + light energy → carbohydrate + oxidized electron donor. In oxygenic photosynthesis water is the electron donor and, since its hydrolysis releases oxygen, the equation for this process is:
