Principles of Biology Photosynthesis and Fermentation The fuel for respiration ultimately comes from photosynthesis All organisms can harvest energy from organic molecules. Plants can make these molecules from inorganic sources by the process of photosynthesis. Life’s energy cycle Photosynthesis and cellular respiration provide energy for life. Photosynthesis o Photosynthesis is the process by which certain organisms use light energy to make sugar and oxygen gas from carbon dioxide and water. o Photosynthesis occurs in chloroplasts o In plants, photosynthesis occurs primarily in chloroplasts in the leaves. The chloroplasts contain stroma and stacks of thylakoids called grana . o Plants produce O2 gas by splitting water. The O 2 produced by photosynthesis is made from the oxygen atoms in water. Photosynthesis occurs in two stages The complete process of photosynthesis consists of two linked sets of reactions, the light reactions and the Calvin cycle . The light reactions convert light energy to chemical energy, producing O
