Assertion : Six molecules of \(C{O_2}\) and 12 molecules of NADPH and 18 ATP are used to form one hexose molecule Reason : Light reaction results in the formation ATP and \(NADP{H_2}\)
1 Both Assertion and Reason are true and Reason is correct explanation of Assertion.
2 Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
3 Assertion is true but Reason is false.

Identify the incorrect statement w.r.t Calvin cycle
1 The first stable intermediate compound formed is phosphoglycerate
2 NADH + \({H^ + }\) produced in light reaction is used to reduce diphosphoglycerate
3 18 Molecules of ATP are synthesised during carbon fixation
4 All are incorrect
Explanation:
The first stable product in \({C_3}\) cycle is 3-PGA. NADPH produced in light reaction is used to reduce 3-phosphoglycerate. 18 ATP is utilised during carbon fixation. Hence, all statements are incorrect.

Which one of the following phenomena in its proper sequence is represented by Calvin cycle?
337033
Carboxylation (\({C_3}\) cycle) is catalysed by
1 Carboxylase
2 RuBP carboxylase
3 RuBP oxygenase
4 Both 2 and 3
Explanation:
Carboxylation of RuBP is catalysed by RuBisCO or RuBP carboxylase oxygenase. It results in the formation of two molecules of 3-PGA (3-Phosphoglyceric acid)

Which of the following pair is mismatched?
1 Photosystem I - Uses the \(\mathrm{P}_{700}\) molecule in its photocenter.
2 Antenna complex - Contains hundreds of pigment molecule.
3 PGA-3-carbon compound.
4 Dark reaction - Takes place in the grana of the chloroplast.
Explanation:
Dark reaction is a thermochemical reaction. It takes place in the stroma of the chloroplast. Dark reaction, also called \(\mathrm{CO}_{2}\) fixation or carbon assimilation, occurs even in the presence of light but it doesn't require light. Dark reaction consists of 3 phases carboxylation, reduction and regeneration of \(\mathrm{CO}_{2}\) acceptor.
