Chlorophyll b degradation (WP2230)
Arabidopsis thaliana
In plants the light harvesting complex around the photosystems contain chlorophyll a and b pigment molecules. both Chlorophyll and b helps in photosynthesis by absorbing light energy. Chlorophyll b is degraded into chlorophyll a and ultimately into phenophytins and pheophorbides.
