Chlorophyll is energized by sunlight
Water molecules split into hydrogen and hydroxyl ions
Carbon (IV) oxide is reduced by hydrogen atoms in NADPH2
Water is formed
Forklaring
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.
