Read the given statements and select the correct option.
Statement 1 : Carboxylation is the most crucial step of Calvin cycle where `CO_(2)` is utilised for the carboxylation of RuBP.
Statement 2: Carboxylation is catalysed by the enzyme RuBis CO which results in the formation of two molecules of 3PGA.

Options

A. Both statement 1 and 2 are correct.
B. Statement 1 is correct but statement 2 is incorrect.
C. Statement 1 is incorrect but statement 2 is correct
D. Both statements 1 and 2 are incorrect.

Answer

A

Explanation

Carboxylation is the fixation of `CO_(2)` into a stable organic intermediate if is the most crucial step of Cavin cycle where `CO_(2)` is utilised for the carboxylation of RuBP through the use of ATP and NADPH generated by the light reactions. This reaction is catalysed by enzyme RuBisCO which results in the formation of two molecules of 3-phosphoglyceric acid or PGA, which is the first stable product of photosynthesis.
