WebThe process of photosynthesis: carbon fixation and reduction C 3 carbon fixation pathway The assimilation of carbon into organic compounds is the result of a complex series of enzymatically regulated chemical reactions—the dark reactions. This term is something of a misnomer, for these reactions can take place in either light or darkness. WebBiological nitrogen fixation is a process by which nitrogen is fixed in plants with the help of certain anaerobic bacteria. Biological nitrogen fixation was discovered by Dutch microbiologist Martinus Beijerinck in 1901. Only certain organisms like prokaryotes, such as bacteria and cyanobacteria, can fix atmospheric nitrogen.
