... What process occurs during the light-independent reactions of photosynthesis?A. In light-dependent reactions, the first stage of photosynthesis, the energy from light propels electrons into a high-energy state. These light-dependent reactions fuel the second stage of photosynthesis which are the light-independent reactions. The light reaction is also known as photolysis reaction and takes place in the presence of light. The Calvin cycle was named after Melvin Calvin. Using the energy carriers formed in the first steps of photosynthesis, the light-independent reactions, or the Calvin cycle, take in CO 2 from the environment. Photosynthesis. Oxygen is ... 11M.2.HL.TZ2.5c: Explain the light-independent reactions of photosynthesis. The light-independent reaction is also referred to as the dark reaction because it does not require light. After three cycles, a three-carbon molecule of G3P leaves the cycle to become part of a carbohydrate molecule. Describe the process of photolysis in photosynthesis. Conceptual overview of light dependent reactions. These reactions occur in the stroma of the chloroplast, which is the fluid-filled region between the thylakoid membrane and inner membrane of the organelle. Photosynthesis. Intro to photosynthesis. These reactions take the light-dependent reactions and perform further chemical processes on them. ATP and NADPH are used in light-independent reactions to make glucose and other carbohydrates. Those two chlorophylls can undergo oxidation upon excitation; they can actually give up an electron in a process called a photoact. Answers: 3, question: Describe the process of light-independent reactions. Markscheme. Email. There are three phases to the light-independent reactions, collectively called the Calvin cycle: carbon fixation, reduction reactions, and ribulose 1,5-bisphosphate (RuBP) regeneration. The thylakoid membrane absorbs photon energy of different wavelengths of light. 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. Another name for the light independent reaction is the Calvin cycle. The light-dependent reactions. An enzyme, RuBisCO, catalyzes a reaction with CO 2 and another molecule, RuBP. The photosystems have pigment molecules. Glucose is needed for cellular respiration. The light-independent reaction converts CO_2 into glucose. It is at this step in the reaction center during photosynthesis that light energy is converted into an excited electron. samantharivera samantharivera ATP is a product of light-dependent reactions. The process of photosynthesis is made up of light dependent reactions (the photo’ part) and sugar making or light independent reactions (the synthesis part). Here is a look at the redox reactions that occur during the Calvin cycle. NADPH is a product of light-dependent reactions. Light dependent reactions Here is an explanation in technical terms: To begin with water is taken … The light-independent reactions of the Calvin cycle can be organized into three basic stages: fixation, reduction, and regeneration. Therefore, the light-independent reaction cannot happen without the light-dependent reaction. The reaction center contains a pair of chlorophyll a molecules with a special property. It usually takes place in the grana of chloroplasts. Section Summary. This is … The light-independent reactions are sometimes called the Calvin cycle because of the cyclical nature of the process. Breaking down photosynthesis stages. Google Classroom Facebook Twitter. Reaction center chlorophylls P700 and P680. The Calvin cycle is a set of light independent redox reactions that occur during photosynthesis and carbon fixation to convert carbon dioxide into the sugar glucose.
