Difference between light dependent reactions and light independent reactions in photosynthesis? -Light independent reactions uses CO2 and the ATP and NADPH from light dependent reactions to produce sugar/ glucose. The light-independent reactions are sometimes called the Calvin cycle because of the cyclical nature of the process. While the light dependent reaction cannot proceed without light availability, the light independent reaction can proceed both in the presence or absence of light. The light dependent and light independent reactions are two stages of photosynthesis that overall utilise light energy to fix carbon dioxide into sugar molecules. the light independent reaction during which the ATP and NADPH produced in light dependent reaction is used to fix carbon dioxide into glucose. Click to see full answer. Following are the important differences between light and dark reaction: Light Reaction. Therefore, the light-independent reaction cannot happen without the light-dependent reaction. The light-independent reactions require carbon dioxide, occur in the stroma, and produce high-energy sugars. 1 See answer . Sunlight then enters the leaf . The actual fixation of carbon dioxide, which diffuses into the leaf from the atmosphere, occurs by a cyclic series of reactions called the Calvin cycle (named after one of the pioneer researchers in this area) A summary of the Calvin cycle is illustrated in . Figure 8.11 The sun emits energy in the form of electromagnetic radiation . B. the light-dependent and light-independent reactions both take place within the membranes of bacterial cells or thylakoid membranes of chloroplasts. After the energy is released, the "empty" energy carriers return to the light-dependent reaction to obtain more energy. It produces ATP and NADPH (reduced NADP) through various processes which are far more detailed. Light-independent photosynthesis. Key Points on Light Reaction The cycle is light-independent because it takes place after the energy has been captured from sunlight. Site of occurrence: A light reaction occurs within the thylakoid membrane, whereas .

It is called light-dependent photosynthesis because it needs light or depends on light to produce organic energy . The light-dependent reactions produce ATP and NADPH; the light-independent reactions use energy stored in ATP and NADPH. We use cookies to provide and improve our services. Although the Calvin Cycle is not directly dependent on light, it is indirectly dependent on light since the necessary energy carriers ( ATP and NADPH) are products of light-dependent reactions. Light-dependent reactions of photosynthesis at the thylakoid membrane. In the light-independent reactions or Calvin cycle, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules. It takes place in the grana of the chloroplast. The light-independent reactions (Calvin cycle) use stored chemical energy from the light-dependent reactions to "fix" CO 2 and create a product that can be converted into glucose. Although the light-independent reactions do not use light as a reactant (and as a result can take place at day or night), they require the products of the light-dependent reactions to function. The energy carriers that move energy from light-dependent reactions to light-independent reactions can be thought of as "full" because they are rich in energy. The light-independent molecules depend on the energy carrier molecules, ATP and NADPH, to drive the construction of new carbohydrate molecules. The Calvin cycle (also known as the Benson- Calvin cycle ) is a set of chemical reactions that take place in chloroplasts during photosynthesis. In photosynthesis, the light-dependent reaction uses light energy from the sun to split water (photolysis). The key difference between light reaction and Calvin cycle is the dependence of light in each type of reaction in photosynthesis. The complete process bears two reactions in which one occurs in the presence of sunlight whereas the other one occurs in the absence of sunlight. Light dependent reactions.
