Which of the following statements about the C4 cycle is true ?

a.) C4 plants uses the enzyme phosphoenolpyruvate carboxylase (PEPCase), rather than rubisco

b.) Unlike rubisco, O2 does not compete with HCO3 − in the carboxylation catalyzed by PEPCase

c.)  initial carboxylation catalyzes in bundle sheath cells, four-carbon acids formed and flow across the diffusion barrier to the mesophyll cells

d.) during decarboxylation, releasing CO2 that is refixed by rubisco via the Calvin–Benson cycle
