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.
The Calvin Cycle is the most common method of carbon fixation. In plants, there are three types of carbon fixation during photosynthesis: C3 â a plant that uses the Calvin Cycle for the initial steps that incorporate CO2 into organic matter, forming a 3-carbon compound as the first stable intermediate.
