Carbon dioxide fixation in the Calvin cycle is catalyzed by:

The enzyme Ribulose bisphosphate carboxylase catalyzes the carboxylation reaction between . . . . . . .

Radioactive $C^{14}$ is given to carbon dioxide and released into the atmosphere. This carbon dioxide is taken up by $RuBP$ in a $C_{3}$ plant. In which compound is the radioactive $C^{14}$ first observed?

$C_3$ plants show optimum photosynthesis at:

In the $C_3$ pathway,the first stable product is $P$,and in the $C_4$ pathway,the first stable product is $Q$. Choose the correct option for $P$ and $Q$.

The path of $CO_2$ in the dark reaction of photosynthesis was successfully traced by using which of the following?
