2. Photosynthesis must be triggered by a catalyst known as what in order for the process to start?
Ribulose-1,5-bisphosphate carboxylase oxygenase (RuBisCO) is an enzyme involved in the first major step of carbon fixation in photosynthesis, a process by which atmospheric carbon dioxide is converted by plants to energy-rich molecules such as glucose. In chemical terms, it catalyzes the carboxylation of ribulose-1,5-bisphosphate to form two molecules of 3-phosphoglycerate. The overall equation for the light-independent reactions in green plants is: 3 CO2 + 9 ATP + 6 NADPH + 6 H+ → C3H6O3-phosphate + 9 ADP + 8 Pi + 6 NADP+ + 3 H2O
