Study Notes
Photosynthesis
- In 1779, Joseph Priestley first published about the process of photosynthesis.
Types of Photosynthesis
- The oldest and most common form of photosynthesis is Oxygenic Photosynthesis.
Early Photosynthetic Organisms
- The reducing agent most likely used by the first photosynthetic organisms was Iron-Sulfur.
Crassulacean Acid Metabolism (CAM) Plants
- CAM plants use an adaptation called Crassulacean Acid Metabolism to conserve water during photosynthesis.
Metabolic Pathways
- The Calvin cycle is prefaced by the Hatch-Slack pathway, which incorporates CO2 into four-carbon compounds.
- The three major metabolic pathways by which photosynthesis is carried out are Oxygenic Photosynthesis, Anoxygenic Photosynthesis, and Crassulacean Acid Metabolism (CAM).
Photosynthesis Process
- Photosynthesis is the process by which light energy is used to assemble sugars from carbon dioxide and a hydrogen and electron source.
