Topic: NEET PYQ
Answer: B. Full step-by-step solution below.
- APhotophosphorylation and non-cyclic electron transport
- BTwo photosystems operating simultaneously
- CPhotophosphorylation and cyclic electron transport
- DOxidative phosphorylation
Correct answer: B
Solution
(b) Emerson’s enhancement effect showed that the rate of photosynthesis increases when red light and far-red light are given together, indicating the presence of two photosystems (PS I and PS II). Red drop supported the involvement of another photosystem in photosynthesis.More Photosynthesis in Plants PYQs
