Photosynthesis in Higher Plants

Solution:
In C3 plants, carboxylation is the initial phase of CO2 assimilation. Carboxylation is the addition of carbon dioxide to another substance called acceptor. Photosynthetic carboxylation requires ribulose-1, 5-biphosphate or RuBP as acceptor of carbon dioxide and RuBP carboxylase or RuBisCO as enzyme. The enzyme was previously called carboxydismutase.
