Plants are the best-known autotrophs, but others exist, including certain types of bacteria and algae (Figure 1). For instance, plants are eaten by grazers who may eventually be a food source for predators and decomposers. Reactants of aerobic respiration. Some of this energy is used to split water into hydrogen and oxygen. Photosynthesis Summary . There are 2 stages in the photosynthesis: light reactions and carbon fixation. Photosynthesis Light Reaction. The three-stage model of photosynthesis starts with absorption of sunlight and ends in the production of glucose. After radiant energy from sunlight is absorbed, the plant converts light energy into a usable form of chemical energy to fuel the plant’s cells. synthesis. The hydrogen electrons of the water molecule then move to a reaction center in the chlorophyll molecule. ADP + NADP + H2O → ATP +NADPH + H ion + O2 The reason why this stage is called “Light Reaction” is because light plays a big part of the reaction, enzymes are also required to catalyse them. An autotroph is an organism that can produce its own food. The overall process of carbon fixation is summarised in the diagram below. Read about our approach to external linking. The flow diagram represents stages of photosynthesis in a leaf. It reflects them instead, so that's the color you see. The three-stage model of photosynthesis starts with absorption of sunlight and ends in the production of glucose. Photosynthesis is a two stage process. ... fact, they work in opposite ways. Photosynthesis takes place through several steps which occur during two stages: the light phase and the dark phase. Next lesson. Religious, moral and philosophical studies. In the process of photosynthesis, sunlight is collected by living organisms and used to produce glucose and other energy-rich, carbon-based compounds. Conceptual overview of light dependent reactions. Photosynthesis is a complex process that can be divided into two or more stages, such light-dependent and light-independent reactions.
