$O^{18}$

Vedclass · Answer

(C) The correct answer is $C$. Ruben and Kamen used the heavy isotope of oxygen,$O^{18}$,in water $(H_2O^{18})$ instead of normal water $(H_2O^{16})$ during their experiments.They observed that the oxygen liberated during photosynthesis contains $O^{18}$ derived from water,not from $CO_2$.The chemical equation for this process is:$6CO_2 + 12H_2O^{18} \xrightarrow{	ext{Light, Chlorophyll}} C_6H_{12}O_6 + 6O_2^{18} + 6H_2O$
