Document Summary

If red light is absorbed, the pigments are excited to a higher energy (but the lowest excited state) and lose that energy through fluorescence. If blue light is absorbed, the pigments are excited to the highest excited state. In the dark they press themselves up against the cell membrane to catch more light. Carboxylation: this is (cid:862)(cid:271)asi(cid:272)(cid:863) c3 photosynthesis because there is a 3 carbon molecule produced, reaction of co2 and water with rubp to create 3-phosphoglycerate, 2. Reduction: atp and nadph are consumed during this steps to convert 3-phosphoglycerate into glyceraldehyde 3-phosphate (which will go on to be converted to carbon output, 3. Regeneration: glyceraldehyde 3-phosphate is used to generate rubp for first step, this process does consume atp, o(cid:448)erall (cid:373)ost car(cid:271)o(cid:374) i(cid:374) the cal(cid:448)i(cid:374) (cid:272)(cid:455)(cid:272)le is re(cid:272)(cid:455)(cid:272)led! Low catalytic rate (it sucks) so a lot is needed to catalyze reaction. Calvin cycle to fix carbon using nadph and atp.
