Given below are two statements: Statement I: The primary CO 2 acceptor in C 4 plants is phosphoenolpyruvate…

Given below are two statements:

Statement I: The primary CO2 acceptor in C4 plants is phosphoenolpyruvate and is found in the mesophyll cells.
Statement II : Mesophyll cells of C4 plants lack RuBisCo enzyme.

In the light of the above statements, choose the correct answer from the options given below :

  1. Both Statement I and Statement II are incorrect
  2. Statement I is correct but Statement II is incorrect
  3. Statement I is incorrect but Statement II is correct
  4. Both Statement I and Statement II are correct

Solution

Phosphoenolpyruvate or PEP is the 3C compound and acts as the primary carbon dioxide acceptor in the mesophyll cells of C4 plants, leading to the formation of OAA, C4 acid. Ribulose-1,5-bisphosphate carboxylase oxygenase (RuBisCO) is an enzyme found in the mesophyll cells present within the C3 plants. In C4 plants, this enzyme is found in the bundle sheath cells.
