Summary and concept check for 8.3






Calvin cycle is one process of photosynthesis and it's called cycle because it regenerates the starting energy continuosly like Krebs cylcle and in calvin cycle's case it's RuBP. Which means sugar with five cearbons.




Equation of Photosynthesis is 6CO2+6H2O to C6H12O6+HO2


Light reaction takes place in the thylakoid membrane. It converts light energy into ATP and NADPH.


Photosynthesis is a first step of ecosystem.




Concept check 8.3


1. Input is carbon dioxide, ATP, and NADPH.


Output is energy- rich sugar molecule.
2.


3.Calvin cycle is called cycle, because it regenerates the starting material in calvin cycle, it's RuBP.


4. The direct product made from photosynthesis is sugar molecule.
