Q6. In Bacterial photosynthesis, hydrogen donar is
Answer : Option BExplaination / Solution: In green plants H2Ois the hydrogen donor and is oxidised to O2 . Some organisms do not release O2 during photosynthesis. When H2S, instead is the hydrogen donor for purple and green sulphur bacteria, the ‘oxidation’ product is sulphur or sulphate depending on the organism.
Answer : Option AExplaination / Solution:
Solarisation is the inhibition of photosynthesis at very high light intensities due to photoxidation of certain compounds and destruction of chlorophyll moleucules.

Answer : Option DExplaination / Solution:
Splitting of the water molecule takes place on the inner side of the membrane, the protons or hydrogen ions that are produced by the splitting of water accumulate within the lumen of the thylakoids.
