Are the chlorophyll molecules in PSI and PSII the same?

No, the chlorophyll molecules in Photosystem I (PSI) and Photosystem II (PSII) are not the same. They differ in absorption spectra and redox properties, allowing them to play distinct roles in the light reactions of photosynthesis.


Why photolysis of water takes place at PSII and not at PSI in thallakoid channel?

Photolysis of water occurs at Photosystem II (PSII) because it has a higher oxidation potential than Photosystem I (PSI). This higher potential allows PSII to extract electrons from water molecules during the light-dependent reactions of photosynthesis. Additionally, the location of the water-splitting complex is specific to PSII, where it is positioned near the oxygen-evolving complex that facilitates water splitting.


What are the clusters of photosystems?

The two clusters of photosystems in plants are Photosystem I (PSI) and Photosystem II (PSII). PSII functions first in the photosynthetic electron transport chain, followed by PSI, and they work together to absorb light energy and carry out the reactions of photosynthesis.


What special pigment do plant cells contain?

Chlorophyll in the chloroplasts and other accesory pigments (p680 in PSII and p700 in PSI)


How is H electrochemical gradient established and maintained in photosynthesis?

The formation of NADPH, the movement of electrons from PSII to PSI, & the splitting of water


What is the difference between 3500 psi concrete and 4000 psi concrete?

500psi


What photosystems are embedded in the electron transport chain?

PSII, PSI, cytocromes, ferrodoxins are the part of ETC. They transport the protons to ATPase to produce ATP.


How are the chlorophyll molecules in PSI and PSII reset?

The chlorophyll molecules in Photosystem I (PSI) and Photosystem II (PSII) are reset when an electron is donated to them from an external source, such as when water is split during the light-dependent reactions of photosynthesis. This replenishes the electrons lost during the light-harvesting process, allowing the chlorophyll molecules to continue their role in capturing and transferring light energy.


What is the compression on a Chevy 366?

150 psi per cylinder with +/- 20 psi difference between cylinders


How do you convert 14.73 psi to 15.025 psi?

To convert 14.73 psi to 15.025 psi, you need to increase the pressure by the difference between the two values. Subtract 14.73 from 15.025, which gives you 0.295 psi. Therefore, you can achieve the conversion by adding 0.295 psi to 14.73 psi, resulting in 15.025 psi.


Write the equation connecting photo system 1 and photosystem 2?

The equation connecting Photosystem I (PSI) and Photosystem II (PSII) in photosynthesis is: 2H2O + 2NADP+ + 8 photons (light) → O2 + 2NADPH + 2H+ + 8 photons (light). This represents the light-dependent reactions in the thylakoid membrane where PSII and PSI work together to drive the production of energy carriers like ATP and NADPH.
