Fotosintesi - Parte II: i cicli C3, C4 e CAM

This video discusses photosynthesis, primarily from an ecological and evolutionary perspective. In this second part of the video, we expand on the RuBisCO enzyme, discuss photorespiration, and delve deeper into the C4 and CAM cycles, which evolved in approximately 10% of land plants as an "alternative" to the C3 cycle to solve major ecological problems. The first part of the video provides a general overview of photosynthesis, with a brief description of the processes that directly depend on light and the Calvin-Benson cycle, the light-independent phase.
