Question:
Name the two important enzymes of the C4 pathway, and explain their role in fixing CO2?
Solution:
Rubisco and PEP case are the two important enzymes of C3 and C4 pathways. Rubisco is the primary CO2 receiver in C3 facilities while PEP case is the main
CO2 receiver for C4 facilities. The important enzyme of the C3 pathway is RUBisCO and C4 is PEPcase. In the Calvin cycle, carboxylation is the most crucial step.
Carbon dioxide is utilized for the carboxylation of RuBP. This is catalyzed by RuBP carboxylase which results in the formation of two molecules of 3-PGA. The primary
carbon dioxide acceptor in the C4 pathway is 3 carbon molecule phosphoenolpyruvate.
