The Light-Independent Reactions of Photosynthesis (College Board AP® Biology) : Study Guide
The Calvin cycle
The light-independent stage of photosynthesis, also referred to as the Calvin cycle, occur in the stroma of chloroplasts
This stage produces complex organic molecules, including carbohydrates such as:
starch
sucrose
cellulose
The Calvin cycle involves the following processes:
carbon dioxide is absorbed from the air and enters the chloroplasts
a series of chemical reactions that involve ATP and NADPH from the light-dependent stage result in carbon dioxide being fixed
six-carbon sugars, e.g., glucose, and other carbon-containing compounds are produced
