A decrease in photosynthetic rate with increased availability of oxygen is called
A decrease in photosynthetic rate with increased availability of oxygen is called
The correct option is A Warburg effect
A. Photorespiration: The inhibition of photosynthesis by high O2 level was termed as Warburg effect. However, the inhibition was observed mostly in C3 plants. The C4 plants were hardly affected by varying O2 concentrations.
B.Richmond Lang effect: The delay of senescence of leaves and other organs of the plants by cytokinins is called Richmond - Lang effect.
C. Blackman's Law of limiting factors: According to this law, when a process depends on a number of factors, its rate is limited by the pace of the slowest factor.
D. The Emerson effect is the increase in the rate of photosynthesis after chloroplasts are exposed to the light of wavelength 670 nm (deep red spectrum) and 700 nm (far red spectrum).
Hence, the correct answer is 'Warburg effect'.
