Solution:
C4 pathway was first reported in members of family Gramineae
(grasses) like sugarcane, maize, sorghum, etc. These C4 plants have a characteristic leaf anatomy called Kranz anatomy. So in
chloroplasts of mesophyll cells -PEPCo (PEP carboylase) is the key enzyme used to fix CO2 in C4 plants Oxaloacetic acid is a 4 -
C compound and is the first stable product so this pathway is known as C4 cycle.
