In sugarcane plant 14CO2{ }^{14} \mathrm{CO}_2 is fixed in malic acid, in which the enzyme that fixes CO2\mathrm{CO}_2 is:In sugarcane plant ^ 14 CO_2 is fixed in malic acid, in which the enzyme that fixes CO_2 is:

Options

  1. Aribulose biphosphate carboxylase
  2. Bphosphoenol pyruvic acid carboxylase
  3. Cribulose phosphate kinase
  4. Dfructose phosphatase

Correct answer

B. phosphoenol pyruvic acid carboxylase

Step-by-step solution

In C4\mathrm{C}_4 plant, in chloroplasts of mesophyll cells PEP carboxylase is the key enzyme used in carbon fixation. Due to this enzyme PEP +CO2+\mathrm{CO}_2 converted into oxaloacetic acid. In sugarcane plant ^ 14 CO_2 is fixed in malic acid, in which the enzyme that fixes CO_2 is:
Caution Sugarcane is a C2C_2 plant.
