Photosynthesis:
Light Reactions
Dark Reactions
Humans and Bioengineering
Oxygen problem where O2 level is too high
...
Systematics
• Photosynthesis is the formation of carbohydrates using the energy of light
...

• Rubisco with the presence of CO2 can generate 3-PGA which then has to form an
aldehyde which is the carboxylation reaction in the Calvin Cycle
...

• PEP- phosphoenolpyruvate produces no net CO2 production at the end
...

• Relies on Carbonate to avoid the oxygen problem
...

• The unit aspect has to do with the concentration of CO2
...
Infrared radiation rises and gets reflected back because of the
elevated levels of CO2 and therefore the infrared radiation is trapped
...

Impact of CO2 elevation on photosynthesis
[Refer to graph]
• The higher the light intensity the higher the carbohydrate formation in the
photosynthetic process
...
No more
Carbohydrates are formed
...

Other factors limit for Example burning of fossil fuels and things like that
...

• Temperature affects rate of enzymatic activity
...

Humans and Bioengineering
Bioengineering Metabolic Pathways:
• Formation of phosphoglycolate that doesn’t allow for the formation of CO2 fixation
...


• Metabolic pathways - modification is a consequence of understanding chloroplasts
...
coli
e) tartonic semialdehyde reductase from Salmonella
f) C + D
g) C + E
h) None of the above
Diversity of Organisms [Chapter 12]
• Systematics has to do with binomial nomenclature
...

• Most of the organisms that are associated with a genus and a species are latin based
