Vedclass · Answer

(A) In the process of photosynthesis,the oxygen released as a byproduct comes from the photolysis of water $(H_2O)$.When water labeled with the heavy isotope of oxygen,$^{18}O$,is provided to the photosynthetic system,the oxygen gas $(O_2)$ released during the light-dependent reactions will also contain the $^{18}O$ isotope.This experiment,famously conducted by Ruben,Hassid,and Kamen,confirmed that the source of oxygen in photosynthesis is water,not carbon dioxide.

If in a photosynthetic system,${H_2O}^{18}$ is provided,what will be the type of oxygen released in the process?
