BiologyPhotosynthesis in Higher PlantsNEET

Match the phenomenon listed under Column I with those listed under Column II. Column I: (A) Warburg effect (B) Pasteur effect (C) Emerson effect (D) Wright effect Column II: (1) Change in gene frequency by chance (2) Postponing senescence in leaves by applying cytokinin (3) Decline in consumption of respiratory substrate due to change from anaerobic to aerobic respiration (4) Inhibitory effect of oxygen on photosynthesis (5) Enhancement of photosynthesis by subjecting chlorophyll to two different wavelengths of light

Answer: (A)

Solution

Warburg effect = inhibition of photosynthesis by high O2 concentration (4). Pasteur effect = decline in respiratory substrate consumption on shifting from anaerobic to aerobic respiration (3).
