Compare and contrast the events of the light reaction with the events of the dark reaction

Dark reactions make use of these organic energy molecules (ATP and NADPH). This reaction cycle is also called Calvin Benison Cycle, and it occurs in the stroma. ATP provides the energy while NADPH provides the electrons required to fix the CO2 (carbon dioxide) into carbohydrates.

Biochemistry, it deals with the chemical constitution, the breakdown and the synthesis of plant and animal products.
