Q40. Both Photosynthesis and respiration rely on electron transport.

Although there are many differences, what do these electron transport chains have in common?

  1. In both, the electron donor (water in the case of photosynthesis, NADH in the case of respiration) is a strong reducing agent
  2. In both, the proteins which shuttle the electrons (Plastoquinone in photosynthesis, Ubiquinone in the case of respiration) are oxidized and reduced
  3. In both, electrons move spontaneously from high to low redox potential.
  4. 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
