Study Notes
Photosynthesis: Converting Light into Chemical Energy
- Photosynthesis is a biological process that converts light energy into chemical energy.
- It is used by many cellular organisms, such as plants, algae, and cyanobacteria.
- The process produces organic compounds, like sugars and starch, which can be used as fuel for the organism.
- Oxygenic photosynthesis is the most common type, where oxygen is produced as a byproduct.
- Carbon dioxide and water are converted into carbohydrates through an endergonic reaction.
- Photosynthesis is essential for maintaining the Earth's oxygen content and providing energy for complex life forms.
- Photoautotrophs are organisms that perform photosynthesis.
- Some bacteria also perform anoxygenic photosynthesis, using bacteriochlorophyll and hydrogen sulfide.
- The oxygen produced during photosynthesis is a byproduct and not used by the organisms themselves.
- Carbohydrates synthesized through photosynthesis are stored as energy reserves.
- Photosynthesis is a fundamental process for the survival and growth of plants and other organisms.
- It is a key factor in the carbon cycle and contributes to the balance of atmospheric gases.
