Study shows anaerobic fermentation metabolites suppress both photosynthesis and aerobic respiration

In the model organism Chlamydomonas reinhardtii, photosynthesis and aerobic respiration take place in chloroplasts and mitochondria, respectively, while anaerobic fermentation can occur independently in the cytoplasm, mitochondria, and chloroplasts. How these three fundamental energy metabolism processes can occur in harmony within a single cell remains largely unexplored.
