Which statement is incorrect :
1 The \(\mathrm{C}_3\) and \(\mathrm{C}_4\) plants respond similarly to \(\mathrm{CO}_2\) concentration
2 At low light conditions, neither \(\mathrm{C}_3\) and \(\mathrm{C}_4\) plants respond to high \(\mathrm{CO}_2\) concentration
3 \(\mathrm{C}_4\) plants attain saturation at much lower \(\mathrm{CO}_2\) concentration (at about \(360 \mu \mathrm{IL}^{-1}\) ) than \(\mathrm{C}_3\) plants (beyond \(450 \mu \mathrm{IL}^{-1}\) )
4 Current availability of \(\mathrm{CO}_2\) levels is limiting to the \(\mathrm{C}_3\) plants
Explanation:
The \(\mathrm{C}_3\) and \(\mathrm{C}_4\) plants respoind differently to \(\mathrm{CO}_2\) concentrations.

What is the product of oxygenase activity of rubisco:
1 Phosphoglycerate
2 Phosphoglycolate
3 1 and 2 both
4 Phosphoglyceraldehyde
Explanation:
In \(\mathrm{C}_3\) plants some \(\mathrm{O}_2\) does bind to RuBisCO, and hence \(\mathrm{CO}_2\) fixation is decreased. Here the RuBP instead of being converted to 2 molecules of PGA binds with \(\mathrm{O}_2\) to form one molecule of phosphoglycerate and phosphoglycolate (2 Carbon) in a pathway called photorespiration.
While the membrane or lymmellae of the grana have both PS-I and PS-II the stroma lamellae membrane lack PS-Il as well as NADP reductase enzyme.
