1. The reactions of photosynthesis make up a biochemical pathway.

A. What are the end product of light and dark reaction of photosynthesis?
B. Explain how the biochemical pathway of photosynthesis recycles many of its own reactions and identify the recycled reactants.
 
a. Light processes occur in the chloroplast's , which employ water and solar energy to make . The dark reaction takes place in the chloroplast's . It creates  from NADPH, ATP and \(CO_2\).
 
b. Light is used to produce ATP and NADPH in the Light processes. These reactants are used in the dark reaction, also known as the , to create  from extra \(CO_2\) molecules. This cycle then produces NAP + ADP + P (inorganic phosphate), which is employed in light processes, where it is combined with water molecules to form ATP and NADPH.
 
2. Where do the light dependent reaction and the Calvin cycle occur in the chloroplast? 
  
a. In the presence of   energy, a light-dependent reaction occurs in the chloroplast's . 
 
b. The  cycle takes place in the chloroplast's .
