Botany - Photosynthesis in Higher Plants Question with Solution | TestHub

Carboxylation is the first reaction in the Calvin cycle wherein the atmospheric carbon-di-oxide forms 3-PGA in presence of the enzyme RUBISCO. Phosphorylation takes place when the ADP gets converted to ATP due to the phosphate addition in the presence of light as the energy source. Photolysis of water occurs when the oxidized chlorophyll molecule takes an electron from water, which releases oxygen. 2-phosphoglycolate is formed when the enzyme RuBPoxygenase splits the molecule of Ribulose 1, 5-biphospate in presence of oxygen. The nitrosomonas bacteria synthesize organic compounds using the energy from reactions involving inorganic chemicals.
