Q. What is the quantum yield of photosynthesis?

NTA AbhyasNTA Abhyas 2020Photosynthesis in Higher Plants

Solution:

By definition the quantum yield of photosynthesis is the molar ratio between oxygen released in photosynthesis (or carbon assimilated) to photons absorbed in the process. It is denoted by $\left(\phi\right)$ .The quantum ratio generally stays <1 as all photons are not absorbed productively.
Typically for every mole of quanta absorbed 0.06 moles of $C O_{2}$ is fixed under normal conditions.
Quantum yield is found to be around 8% in the photosynthesis process.
