Cytochrome pumps hydrogen ions
WebThe Cytochrome complex pumps hydrogen ions into the thylakoid lumen 2. Hydrogen ion concentration is low in stroma as compared to the thylakoid. 3. Oxygen is reduced to water during this reaction. 4. Light photons energizes electrons in chlorophyll. 5. NADP+ is reduced to NADPH. WebThe cytochrome complex, an enzyme composed of two protein complexes, transfers the electrons from the carrier molecule plastoquinone (Pq) to the protein plastocyanin (Pc), thus enabling both the transfer of protons across the thylakoid membrane and the transfer of electrons from PSII to PSI.

This complex protein acts as a tiny generator, turned by the force of the hydrogen … WebThe cytochromes hold an oxygen molecule very tightly between the iron and copper ions until the oxygen is completely reduced by the gain of two electrons. The reduced oxygen then picks up two hydrogen ions from the surrounding medium to make water (H 2 O).
