A Level Biology Revision (Year 13) "Two Key Reactions in Photosynthesis"
Freesciencelessons・2 minutes read
Photosynthesis is a process in autotrophic organisms where light energy converts carbon dioxide and water into glucose and oxygen. Light-dependent reactions produce ATP and reduced NADP, which the light-independent reactions then use to create glucose.
Insights
- Light-dependent reactions in photosynthesis produce ATP and reduced NADP, requiring light to function, while light-independent reactions use these products to create glucose without needing light.
- Without light, the light-independent reactions in photosynthesis cannot proceed due to the absence of ATP and reduced NADP generated by the light-dependent reactions.

Photosynthesis: Light and Dark Reactions Explained
- Photosynthesis is a process carried out by autotrophic organisms like plants and algae, where carbon dioxide and water react with light energy to produce glucose and oxygen. The reactions occur in chloroplasts, with the light-dependent reactions happening on thid membranes to produce ATP and reduced nadp, while the light-independent reactions in the stroma use these products to create glucose from carbon dioxide.
- The light-dependent reactions require light to function and produce ATP and reduced nadp, while the light-independent reactions do not need light but rely on the products from the light-dependent reactions to create glucose. If light is absent, the light-independent reactions cease due to the lack of ATP and reduced nadp.
