Emerson's enhancement effect and red drop have been instrumental in the discovery of:

Options

  1. APhotophosphorylation and non - cyclic electron transport
  2. BTwo photosystems operating simultaneously
  3. CPhotophosphorylation and cyclic electron transport
  4. DOxidative phosphorylation

Correct answer

B. Two photosystems operating simultaneously

Step-by-step solution

The red drop effect occurs due to decreased functioning of PS-II beyond 680 nm and when both PS-I and PS-II are functioning together there is an enhancement in quantum yield. In PS I the reaction centre chlorophyll a has an absorption peak at 700 nm.
