Cyanobacteria, also known as blue-green bacteria, are photosynthesizing bacteria, and their morphologically similar ancestors are thought to be the first photosynthesizing organisms. Outside of the thylakoid is a fluid called the stroma (“6”), which is analogous to the cytosol of a eukaryotic cell, or the matrix of a mitochondrion. Prokaryotic photosynthesizers preceded them by two billion years. In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and that energy is converted into stored chemical energy. The process of photosynthesis converts light energy to chemical energy, which can be used by organisms for different metabolic processes. Photosynthesis takes place through several steps which occur during two stages: the light phase and the dark phase. These electrons and protons are used to reduce the oxidized electron carrier NADP+ (shown at “8”) into its reduced, high energy form, NADPH (shown at “5”). In the last tutorial, we looked at the overall equation for photosynthesis: 6CO 2 + 6H 2 O + light energy –> C 6 H 12 O 6 + 6O 2. Here’s a hint. The two stages of photosynthesis are light reactions and the Calvin cycle; light reactions take place first, forming the photo portion of photosynthesis, while the Calvin cycle follows, completing the cycle with several steps involving photosynthesis. 6co 2 6h 2 o light energy c 6 h 12 o 6 6o 2.
