Question:

Phosphoenol pyruvate (PEP) is the primary CO₂ acceptor in

Options:

1. C₃-plants
2. C₄-plants
3. C₂-plants
4. C₃ and C₄-plants

Solution:

(2) Phosphoenol Pyruvate (PEP) is found in the mesophyll cell, which accepts the atmospheric CO₂ in C₄-plants and converts it to oxaloacetate—a C₄ compound. It is the first stable compound of C₄-plants. Concept Enhancer C₄-plants possess special adaptation anatomy in their leaves to cope up the photorespiratory losses. There are dimorphic chloroplast present in them—agranal in bundle sheath cells and granal in mesophyll cells.
