Select an incorrect statement for Biosynthetic phase of photosynthesis
1 Use of radioactive \({N_{15}}\) in algal photosynthesis studies led to the discovery
2 This process is independent on the products of the light reaction
3 OAA and PGA either is formed depending on the type of morphology of the plant
4 1 and 2
Explanation:
Radioactive \({C_{14}}\) in algal photosynthesis led to the discovery of the \({C_3}\) cycle. The dark reaction thought light-independent, is dependent on the products of light reaction. If its a \({C_3}\) plant, PGA is the first stable product formed after carboxylation. If its a \({C_4}\) plant, OAA is formed as first stable product after carboxylation.

Select an incorrect statement for \({C_3}\) cycle
1 The regeneration of RuBP from glyceraldehyde- 3-phosphate requires 2 ATP molecule each
2 With the oxidation of PGA, glyceraldehyde 3-phosphate is formed.
3 \({C_3}\) cycle occurs only in \({C_3}\) plants
4 All are incorrect
Explanation:
The regeneration of RuBP from glyceraldehyde-3-phosphate requires 1 ATP molecule each. With the reduction of PGA, glyceraldehyde-3-phosphate is formed. \({C_3}\) cycle is a common pathway in all kinds of plants. Hence, all statements are incorrect.

The outcome of Calvin cycle includes:
1 6, 18 ATP, 12 NADHP
2 One glucose, 18 ATP, 12 NADHP
3 6,18 ADP, 12 NADP
4 One glucose, 18 ADP, 12 NADP
Explanation:
Calvin cycle is the sequence of photosynthetic biosynthetic phase in which ribulose-5-phosphate is carboxylated, converted to three-carbon carbohydrate precursors and regenerated. It is also called the reductive pentose phosphate cycle. The reaction of Calvin cycle may be summed up as: \(6 \mathrm{CO}_{2}+18 \mathrm{ATP}+12 \mathrm{NADPH}+12 \mathrm{H}^{+}\) \(\xrightarrow[\text { dark resolution }]{\text { Enzymes of }} 6 \mathrm{RuBP}+\mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}\) \(+18 \mathrm{ADP}+12 \mathrm{Pi}+12 \mathrm{NADP}+6 \mathrm{H}_{2} \mathrm{O}\)
