Vedclass · Answer

(D) In $1941$, $Samuel 	ext{ } Ruben$, $William 	ext{ } Hassid$, and $Martin 	ext{ } Kamen$ used the heavy isotope of oxygen $(^{18}O)$ to trace the source of oxygen evolved during photosynthesis. They performed experiments using the green alga $Chlorella 	ext{ } pyrenoidosa$. By providing water labeled with $^{18}O$ $(H_2^{18}O)$, they observed that the oxygen released as a byproduct was also labeled with $^{18}O$. This confirmed that the oxygen released during photosynthesis is derived from the splitting of water molecules $(photolysis 	ext{ } of 	ext{ } water)$, not from carbon dioxide $(CO_2)$.
