Carbon Fixation: Pathways and Organisms

This lecture covers the process of carbon fixation, where CO2 is converted to organic carbon by autotrophic organisms. It explains the Calvin cycle, reductive citric acid cycle, and reductive acetyl-coA pathway, highlighting key enzymes and organisms involved. The lecture also discusses the hydroxypropionate bi-cycle and the two hydroxybutyrate cycles, emphasizing the different pathways used by various organisms for carbon fixation.
