Q40. Both Photosynthesis and respiration rely on electron transport. Although there are many differences, what do these electron transport chains have in common? In both, the electron donor (water in the case of photosynthesis, NADH in the case of respiration) is a strong reducing agent In both, the proteins which shuttle the electrons (Plastoquinone in photosynthesis, Ubiquinone in the case of respiration) are oxidized and reduced In both, electrons move spontaneously from high to low redox potential. In both, chemiosmosis results in the production of ATP A. 1,2 and 3 B. 1 and 3 C. 2 and 4 D. 4 only E. All of 1, 2, 3 and 4 are correct

Q21. Photosynthesis is an oxidation-reduction process. Which of the following statements about this redox process is correct? The oxidation of NADPH by the Calvin Cycle is linked to the reduction of CO2. In the electron transport chain, plastocyanin is easier to be oxidized than PQ. Following light absorption H2O is oxidized to O2. Absorption of light by P700 makes it easier to be reduced. A. 1, 2 and 3 B. 1 and 3 C. 2 and 4 D. 4 only E. All of 1,2,3 and 4 are correct
The 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?

31 Think about the average yield of ATP in eukaryotic cells. Is it stable or variable? The yield is variable because the demand for the products is variable. ATP isn't always required, so there are time when the cell takes break to reserve sugars. The yield is steady because the enzymes and complexes used in the process are completely dedicated to cellular respiration, therefore, the process runs smoothly from start to finish every time. There are not often hang ups, fits, and starts as the products progress.
