P700* Has the Most Negative Standard Reduction Potential Found in Nature In photosystem I. P700 in its ground state has an
To propose:
In the P700 light reaction, energy efficiency should be determined.
Introduction:
The P700 is also known as primary donor photosystem I which is the chlorophyll that reacts at the center. This molecule associates with the photosystem I and has 700 nm the absorption spectrum.
Explanation of Solution
The equation of quantum light energy is given as,
We have,
Substituting we have,
So hence,
P700 energy capture is calculated by the change of free energy of Gibb that is divided by one 700 nm photon for P700

- Melvin Calvin and Andrew Benson determined the steps in the light-independent reactions of photosynthesis by exposing the green alga Chlorella to CO2 labeled with the radioisotope carbon 14. By looking at which compounds the C14 ended up in, they were able to identify all intermediates in this cyclic pathway. Why did they predict correctly that the same set of intermediates would be formed in the light reaction in land plants?arrow_forwardThe Overall Free Energy Change for Photosynthetic NADP+ Reduction What is the overall free energy change (G) for noncyclic photosynthetic electron transport? 4 (700-nm photons) + 4 (680-nm photons) + 2 H2O + 2 NADP+O2 + 2 NADPH + 2H+arrow_forwardThe Relative Efficiency of ATP Synthesis in Noncyclic versus Cyclic Photophosphorylation If noncyclic photosynthetic electron transport leads to the translocation of 7 H+/2e- and cyclic photosynthetic electron transport leads to the translocation of 2 H+/e-, what is the relative photosynthetic efficiency of ATP synthesis (expressed as the number of photons absorbed per ATP synthesized) for noncyclic versus cyclic photophosphorylation?

Also how does charge become offset during water oxidation rxns?.arrow_forwardIn cyclic photophosphorylation, it is estimated that two electrons must be passed through the cycle to pump enough protons to generate one ATP. Assuming that the ΔG for hydrolysis of ATP under conditions existing in the chloroplast is about -50 kJ/mol, what is the corresponding percent efficiency of cyclic photophosphorylation, using light of 700 nm?arrow_forwardThere are two photosystems ( I and II) involved in the light-dependent reactions of photosynthesis.
