설명
Dark Reaction is the second step in the mechanism of photosynthesis.
- The chemical processes of photosynthesis occurring independently of light are called dark reactions. It takes place in the stroma of the chloroplast.
- Dark reactions of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. So dark reaction is an enzymatic phase of photosynthesis.
