Identify the correct statements regarding the light reaction of photosynthesis : (a) The stroma lamellae membranes lack PS II as well as NADP reductase enzyme. (b) The reaction centre of Photosystem II has an absorption peak at 700 nm. (c) The CF₁ part of ATP synthase is embedded in the thylakoid membrane and forms a transmembrane channel. (d) Cyclic photophosphorylation results in the synthesis of ATP, but not of NA
Options
- A(a), (b) and (d)
- B(a), (d) and (e)
- C(b), (c) and (e)
- D(c), (d) and (e)
Correct answer
B. (a), (d) and (e)
Step-by-step solution
Statement (a) is correct because stroma lamellae membranes possess only PS I and lack PS II and NADP reductase enzyme. Statement (b) is incorrect because the reaction centre of Photosystem II (PS II) has an absorption peak at 680 nm, while Photosystem I (PS I) has an absorption peak at 700 nm. Statement (c) is incorrect because the CF₀ part of ATP synthase is embedded in the thylakoid membrane and forms a transmembrane channel, whereas the CF₁ part protrudes on the outer surface of the thylakoid membrane.
