Probably the same as any other major... probably even shorter than some (such as pre-med), so 4 years. For my school, you need Intro, Research Methods, Stats, 6 electives and 3 courses from another social science (I chose anthropology, but you can do political science, economics, psychology, etc).
1 Rubisco, the enzyme that is responsible for carbon fixation (combining CO2 with RuBP), can also add O2 to RuBP. 2  When the O2 concentration within a leaf becomes greater than the CO2 concentration, rubisco will add O2 to RuBP instead of CO2.  The resulting molecule cannot be used in the Calvin cycle.
C3 carbon fixation pathwayEncyclopÃ¦dia Britannica, Inc.The assimilation of carbon into organic compounds is the result of a complex series of enzymatically regulated chemical reactionsâthe dark reactions. This term is something of a misnomer, for these reactions can take place in either light or darkness.
