Question

CO2 acceptor and carboxylating enzyme in C3 plants are respectively​

Answer 1

The C3 cycle is a cyclic process of reduction of carbon dioxide in which the first stable product is a three-carbon compound which is 3-phosphoglyceric acid or 3 PGA. In the cycle the carbon dioxide acceptor molecule is RuBP and the enzyme catalyzing this reaction is RuBP carboxylase.

Answer 2

Answer:

$CO_{2}$ acceptor and the enzyme responsible for carboxylation in C3 plants are RuBP and RUBISCO respectively.

Explanation:

• The carbon-fixing reaction response of photosynthesis includes a cyclic series of responses, frequently called the Calvin cycle or Calvin-Benson-Bassham or C3 pathway.

• In carboxylation or carbon fixation of dark reaction, three molecules of CO₂ join with three molecules of 5C compound called ribulose-1, 5-diphosphate, most often spelt as ribulose bisphosphate (RuBP), which is the acceptor molecule of $CO_{2}$, bringing about a shaky or unstable intermediate 6-carbon compound.

• Carboxylation of a molecule of CO₂ to RuBP is catalyzed by the versatile enzyme RuBP carboxylase or Rubisco.

• The subsequent 6C compound is exceptionally unsteady. This molecule rapidly separates to give two molecules of 3-phosphoglycerate (3PG), likewise called phosphoglyceric acid(PGA).

• Hence we can say the carbon dioxide acceptor in the Calvin cycle or C3 cycle is a five-carbon ketose sugar- Ribulose bisphosphate (RuBP). Its chemical name is Ribulose 1,5-diphosphate.
• The enzyme responsible for primary carboxylation in C3 plants is RuBisCO, which stands for Ribulose Bisphosphate Carboxylase-Oxygenase.

Hence $CO_{2}$ acceptor and the enzyme responsible for carboxylation in C3 plants are RuBP and RUBISCO respectively.
