General Biology BIO121 Yeast Fermentation Lab Introduction Organisms stay alive by the utilization of energy through metabolism. The energy acquiring pathways in photosynthesis convert radiant energy from the sun into the chemical bond energy of carbohydrates. This photosynthetic process is limited to the producers or autotrophs, which include plants, photosynthetic bacteria and some protists....
