Light-dependent reactions
-takes place in grana-releases oxygen
light-independent reactions-fixes carbon dioxide-takes place in stroma-
Explanation:
Photosynthesis in plants takes place in two steps to produce glucose and oxygen.
These are:
Light-dependent: In this phase, the molecules required for light independent reaction are made. These are ATP and NADPH. The machinery required for this process is in photosystems, which absorb light in reaction centres and get ATP and NADPH produced. In this process, oxygen is released as a by product. It takes place in the grana of thylakoid membrane.
Light-independents also called as Calvin Cycle or dark reaction: This is the bio synthetic phase of photosynthesis in which glucose is produced by reducing carbon dioxide using the ATP and NADPH from the light reaction.
It takes place in the stroma of the (outside thylakoid membrane) of chlorophyll.
Three important steps of dark reactions are:
Carbon fixation
Reduction of carbon dioxide
formation of ribulose 1,5 bisphosphate.
