Figure 6From: Evolution of energy metabolism and its compartmentation in KinetoplastidaEvolution of Kinetoplastida and Euglenida. A. Acquisition of a chloroplast by secondary endosymbiosis. B. Possible evolutionary scenarios how the secondary endosymbiont was lost in the kinetoplastid lineage but left its traces in different cell compartments of extant organisms. Peroxisomes evolved into glycosomes by the acquisition of pathways of carbohydrate metabolism.Back to article page
