$C_3$ plants mein $CO_2$ acceptor aur carboxylating enzyme kramashah kaun se hain?

The site for the $Calvin$ cycle is .......

$3 CO_{2} + 9 ATP + 6 NADPH + \text{water} \rightarrow \text{glyceraldehyde 3-phosphate} + 9 ADP + 6 NADP^{+} + 8 \Pi$. Analyse the above reaction and answer the following questions:
$(a)$ How many molecules of $ATP$ and $NADPH$ are required to fix one molecule of $CO_{2}$?
$(b)$ Where in the chloroplast does this process occur?

$A$: Biosynthetic phase of photosynthesis depends directly on the presence of light.
$R$: Both $ATP$ and $NADPH$ are not essential for the assimilation of $CO_2$ to carbohydrates.

Radioactive $C^{14}$ is incorporated into $CO_2$ and released into the atmosphere. This $CO_2$ is taken up by $RuBP$ in a $C_3$ plant. In which compound is the radioactive $C^{14}$ first detected?

Photosynthesis consists of essentially two biological reaction systems,one followed by the other. The second of these systems does which of the following?
