As temperature increases the quantum yield of photosynthesis

As temperature increases, the quantum yield of photosynthesis in C3 plants is directly affected by (Explain your answer.)

The increasing ratio of CO₂ to O₂ in the gas phase

The increasing ratio of CO₂ to O₂ in the aqueous phase

The decreasing ratio of CO₂ to O₂ in the aqueous phase

Solution

The quantum yield () of photosynthesis is defined as the molar ratio between oxygen released in photosynthesis (or carbon assimilated) to photons absorbed in the process The quantum yield is, therefore, equal to the ratio of photosynthetically stored radiation (PSR) to the energy absorbed photosynthetically usable radiation (PUR)

thus correct answer is the increasing ratio of co2 to o2 in gas phase
