Answer 1

Radioisotopes, like heavy isotopes of carbon (i.e., $C^{14}$ ) and oxygen (i.e., $O^{18}$ ) were used in photosynthesis. $C^{14}$ labelled carbon dioxide was used by Calvin and coworkers to trace the path of carbon in dark reaction, whereas water containing $O^{18}$ was used by Ruben and Kamen to confirm that the source of oxygen released in photosynthesis is water not carbon dioxide.

Answer 2

Radioisotopes, like heavy isotopes of carbon (i.e.,

C^{14}

) and oxygen (i.e.,

O^{18}

) were used in photosynthesis.

C^{14}

labelled carbon dioxide was used by Calvin and coworkers to trace the path of carbon in dark reaction, whereas water containing

O^{18}

was used by Ruben and Kamen to confirm that the source of oxygen released in photosynthesis is water not carbon dioxide.
