Emerson's enhancement effect and red drop have been instrumental in the discovery of:
Photophosphorylation and non - cyclic electron transport
Two photosystems operating simultaneously
Photophosphorylation and cyclic electron transport
Oxidative phosphorylation
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.
