$ATP$ is produced during:

Provide the full names for the following abbreviations:
$(1)$ $NADP$
$(2)$ $ATP$

According to one estimate,how many $kg$ of carbon is fixed in the biosphere through photosynthesis annually?

Match the following columns:

Column-$I$	Column-$II$
$A$. $PGA$	$P$. Act as oxygenase enzyme
$B$. $OAA$	$Q$. Primary acceptor of $CO_2$
$C$. RuBisCO	$R$. First product of $C_4$ pathway
$D$. RuBP	$S$. First product of $C_3$ pathway

Assertion $:-$ There is not a complete one-to-one overlap between the absorption spectrum of chlorophyll $a$ and the action spectrum of photosynthesis.
Reason $:$ Most of the photosynthesis takes place in the blue and red regions of the spectrum,but some photosynthesis does take place at the other wavelengths of the visible spectrum.

Choose the correct sentence$(s)$ from the following:
$(i).$ In $C_4$ plants,the first $CO_2$ acceptor is $PEP$.
$(ii).$ Light energy is absorbed by $PS-II$ at $680 \ nm$ in the process of photosynthesis.
$(iii).$ The $P_{680}$ chlorophyll system is present in $PS-I$.
