Question
Chapter 21, Problem 8P
Interpretation Introduction
To calculate:
Photons required by the Photophosphorylation of Rhodopseudomonas viridis to synthesize three ATPs.
Introduction:
The enzyme of ATP synthase produces the ATP (adenosine triphosphate) which the molecule that helps in storing the energy. In all organisms this ATP is used as the energy currency of cells.

Calculate (in kJ/mol) the energy that is required by the Rhodopseudomonas viridis photophosphorylation system to synthesize 3 ATP?
(Assume that the R. viridis F1F-ATP synthase c-subunit rotor contains 12 c-subunits and that the R. viridis cytochrome b/c complex translocates 2 H/e". Also assume that the wavelength of lig!
is 680 nm.)

Pathway of CO2 Assimilation in Maize
If a maize (corn) plant is illuminated in the presence of 1"CO2, after about 1 second, more
than 90% of all the radioactivity incorporated in the leaves is found at C-4 of malate,
aspartate, and oxaloacetate. Only after 60 seconds does 14C appear at C-1 of 3-
phosphoglycerate. Explain.
ATP Consumption by Root Nodules in Legumes
Bacteria residing in the root nodules of the pea plant consume more than 20% of the ATP
produced by the plant. Suggest why these bacteria consume so much ATP.
Photosyntheis related question (s):
When protons move out of the thylakoid, are they moving up or down their concentration gradient? (From low to high concentration or from high to low concentration?)
What protein(s) facilitate the transport of protons out of the thylakoid?
We can write the formula for photosynthesis as follows:
6 H2O + 6 CO2 + light energy → C6H12O6 + 6 O2
How would you write a formula for the light reactions? Include ATP, ADP, NADP and NADPH as relevant?
How would you write a formula for the Calvin cycle? Include ATP, ADP, NADP and NADPH as relevant.
