Biology. Photosynthesis has two main stages: light reactions and the Calvin cycle; the Calvin cycle has three stages called carbon fixation, reduction and regeneration of RuBP. Successive steps in the light reaction phase see the conversion of NADP molecules into NADPH compounds. Photosynthesis is a complex process that can be divided into two or more stages, such light-dependent and light-independent reactions. The first two stages of photosynthesis require light and are commonly known as the. [f] No. While the mechanisms of photosynthesis are complex, the overall reaction is as follows: carbon dioxide + sunlight + water --> glucose (sugar) + molecular oxygen (O2). The second of two major stages in photosynthesis (following the light reactions), involving atmospheric CO2 fixation and reduction of the fixed carbon into carbohydrate. what does the plant release after the second stage of photosynthesis? Like mitochondria (another endosymbiont), chloroplasts have a double membrane, a vestige of ancient endocytosis (when its cyanobacterial ancestor was engulfed by a larger cell and, for some reason, was not digested). Looking at a chloroplast up close, you can see several vestiges of its bacterial origins. Which part shows where water would enter the leaf? The first generates energy in ATP, while the second phase – also identified by the name of the Calvin cycle – enables the conversion of inorganic carbon (carbon … The reaction takes place on thylakoids in the chloroplast.
