Question

Referring to the figure below(first picture) explain photosynthetic electron transport. Then compare the process outlined in figure with figure 1, What are the similarities and differences?

OC PSII e 2H₂O O₂ + 4H+ bom e PQ Cyt-bef H+ ADP H+ H₂ 2H+ ATP e Active site 4F45 H₂ase PsaCF PsaD OPSI Oxygenic photosynthesis involving PSII & PSI PC Cyt-bof Acetate ? H+ e 000000 NDA2 e PQ Glucose e Complex I (NDH1) H+ Photomixotrophy involving only PSI Trends in Biotechnology Figure 1. Hydrogenases (H₂ases) were genetically attached to photosystem (PS)I to intercept electrons for H₂ production. H₂ production was light driven both in the engineered cyanobacterial strain (PsaD-HoxYH) as well as in the engineered algal strain (H1). The cyanobacterial NiFe-H₂ase HoxYH was fused to PSI subunit PsaD, whereas the algal FeFe-H₂ase HydA2 was inserted into the PSI subunit PsaC. H₂ production was partly driven by water oxidation at PSII as desired. In addition, glucose provided electrons for cyanobacterial photosynthetic H₂ production in the mutant strain. If acetate did likewise contribute to photoH₂ production in H1 is unclear, as low PSI-HydA2 levels in relation to PSII kept the PQ pool reduced in this mutant.
