Interpretation Introduction
To calculate:
Introduction:
PSII is a complex protein which helps in electron transfer to plastoquinone from water using the light energy for driving. This produces oxygen and reduces the plastoquinone release into the membrane of photosynthesis.

In 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 AG for hydrolysis of ATP under conditions existing in
the chloroplast is about –50 kJ/mol, what is the corresponding percent ef-
ficiency of cyclic photophosphorylation, using light of 700 nm?

However, the pH(lumen) – pH (stroma) is much larger, about 3.4. Calculate delta psi (the electric potential) for the thylakoid membrane, given that ∆G of proton transport is about the same as for the mitochondrion. Then comment on its permeability to ions, compared to the mitochondrial inner membrane’s permeability to ions.arrow_forward
