Question

What is called Warburg's effect on photosynthesis [MP PMT 2003]
A) Low rate of the process due to {{O}_{2}}
supply
B) Low rate of the process due toC{{O}_{2}}
supply
C) Both [a] and [b]
D) None of the above

Answer 1

Low rate of the process due toC{{O}_{2}}
supply
➡️ is called Warburg's effect on photosynthesis

Answer 2

A) Low rate of the process due to {{O}_{2}}

supply

In plant physiology, the Warburg effect is the decrease in the rate of photosynthesis due to high oxygen concentrations. Oxygen is a competitive inhibitor of carbon dioxide fixation by RuBisCO which initiates photosynthesis. Furthermore, oxygen stimulates photorespiration which reduces photosynthetic output.
