Question
Which of the following are correct about C₄ cycle
and C₄ plant? A. Phosphoenolpyruvate carboxylase is located in cytosol B. C₄ cycle occurs in the chloroplasts of bundle sheath cells C. C₄ cycle is a CO₂ enrichment cycle D. C₄ cycle occurs in the chloroplasts of mesophyll cells.Solution
In C₄ plants, the initial step of the C₄ cycle involves the enzyme PEP carboxylase, which catalyzes the fixation of CO₂ to form oxaloacetate in the cytosol of mesophyll cells. After the initial fixation of CO₂ in the mesophyll cells, the C₄ compound (oxaloacetate) is transported to the bundle sheath cells, where it is decarboxylated to release CO₂ , which then enters the Calvin cycle. The C₄ cycle takes place in the chloroplasts of bundle sheath cells.
