The initial important set of processes in photosynthesis, in which light energy is basically transformed into chemical energy as ATP and NADPH, takes place across the chloroplast thylakoid membranes, between the chloroplast stroma and the thylakoid space. But let's focus first on the light-dependent reactions. In plant cells, the light-dependent reactions occur in the chloroplast thylakoid membrane. Favorite Answer. Discuss the products of the light-dependent reactions and the significance of these materials to the production of glucose: Student Answer: The light-dependent reactions are complex metabolic pathways in which charged particles (protons and electrons from water) are separated, producing an electro-chemical difference on two sides of a membrane. The end products of the light-dependent reactions that need the presence of light to occur are ATP and NADPH. It is also known as ‘photolysis,’ meaning occurring in the presence of light. The hydrogen is converted to NADPH, which is then used in the light-independent reactions. The light-dependent reactions and then you have the light independent reactions. I don't like using the word dark reaction because it actually occurs while the sun is outside. When a chlorophyll a molecule within the reaction center of PSII absorbs a photon, the electron in this molecule attains a … *** What are the products of the light dependent reactions? Light dependent reactions is a set of biochemical processes that require light in order for photosynthesis to occur. Which of them is an inference? 7 years ago. In light-dependent reaction, the absorbed energy is converted into chemical energy in the form of ATP whereas in case of light-independent reaction, glucose molecule is produced by utilizing environmental CO 2 and the products of light-dependent reactions- ATP and NADPH. In PSII, energy from sunlight is used to split water, which releases two electrons, two hydrogen atoms, and one oxygen atom. 1 Answer. The light-independent reactions can proceed once products (NADPH and ATP) of the light-dependent reactions are present in the chloroplast. A light-dependent reaction or light reaction is a chemical reaction that takes place in the presence of light. B. Pigments in the photocenter absorb light. The photosystem is the arrangement of pigments, including chlorophyll within thylakoids. Added 7/24/2019 6:10:17 AM The process of light reaction is given below- Light-Dependent Reactions of Photosynthesis. ATP, NADPH, and O2. pls follow me and mark me as brainliest Photosynthesis occurs in two stages: light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH; and, the light-independent reactions use these products to … We answer the basic questions and break it down in an easy-to-understand format. Here is an explanation in technical terms: To begin with water is taken … answers In light-dependent reactions, the energy from sunlight is absorbed by chlorophyll and converted into chemical energy in the form of electron carrier molecules like ATP and NADPH. Products of these reactions are adenosine triphosphate and reduced nicotinamide adenine dinucleotide phosphate (NADPH). The light-dependent reactions begin in a grouping of pigment molecules and proteins called a photosystem. The pigment, chlorophyll, which is required for the process is present on the membrane of these thylakoids and this is where the light reaction occurs. Light provides the energy needed to break apart water molecule. The complete photosynthesis process relies on a coordinated functioning of both the light-dependent and dark reactions to produce carbohydrates from light, water and carbon dioxide. 3. The chloroplasts are double-membraned cell organelles that are comprised of stacked disc-like structures known as thylakoids. Light reaction is the first stage of photosynthesis process in which solar energy is converted into chemical energy in the form of ATP and NADPH. The overall purpose of the light-dependent reactions is to convert light energy into chemical energy. The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. The products of the light-dependent reactions, ATP and NADPH, are both required for the endergonic light-independent reactions. The protein complexes and the pigment molecules help in the production of NADPH and ATP. The exergonic light-dependent reactions of photosynthesis convert light energy into chemical energy, producing ATP and NADPH. The light reaction of photosynthesis initiates only when it is supplied with light energy. The products of the light-dependent reactions, ATP and NADPH, are both required for the endergonic light-independent reactions. O2, ATP, NADPH - out. The answer to this question is ATP and NADPH. The reaction is also called the Calvin cycle. C.ATP synthase allows H+ ions to pass througb the thylakoid membrane. The reactions are known as the Calvin cycle, and they take place in the stroma of the chloroplast. The process of photosynthesis is made up of light dependent reactions (the photo’ part) and sugar making or light independent reactions (the synthesis part). What are the products of the light-dependent reactions of photosynthesis? The exergonic light-dependent reactions of photosynthesis convert light energy into chemical energy, producing ATP and NADPH. Median response time is 34 minutes and may be longer for new subjects. Light dependent reactions. Reason They are dependent on light for the excitation of pigments. Answer Save. The end products of the light-dependent reactions that need the presence of light to occur are ATP and NADPH. The light reaction of light dependent reaction occurs in the chloroplast of the mesophyll cells of the leaves. Log in for more information. A.oxygen gas and glucose B.

The light-dependent reactions can be summarized as follows: 12 H 2 O + 12 NADP + + 18 ADP + 18 P i + light and chlorophyll yields . The plant is producing oxygen. *Response times vary by subject and question complexity. The Calvin cycle uses the energy from short-lived electronically excited carriers to convert carbon dioxide and water into organic compounds [4] that can be used by the organism (and by animals that feed on it). Still have questions? The reactants are replenished by the light-dependent reactions from the Calvin cycle products ADP and NADP +. What are the substrates and products of the light-dependent reaction? The products of the light-dependent reactions, ATP and NADPH, are both required for the endergonic light-independent reactions. Light, water, ADP, Pi, NADP+ - in. In this process light energy is converted to chemical energy in the form of energy reserving molecules ATP and NADPH. The end products of the light dependent reaction are ATP, NADPH, O 2 and water. The diagram above - based on the Z-scheme - suggests the amount of energy in each compound and also partly explains their location in the membranes as energy, electrons, and H+ are passed between them, rather like a pinball game. The light dependent reaction is the initial step of the process of photosynthesis, by which plants can store energy from sun light. These reactions occur in the thylakoids of the chloroplasts. Most photosynthetic organisms capture visible light, although there are some that use infrared light. The products of light dependent reactions are ATP, oxygen and NADPH. Formerly Peter S. Lv 7. In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and converted into stored chemical energy, in the form of the electron carrier molecule NADPH (nicotinamide adenine dinucleotide phosphate) and the energy currency molecule ATP (adenosine triphosphate). This chemical energy will be used by the Calvin cycle to fuel the assembly of sugar molecules. See also:Calvin cycle In photosynthesis, a light-dependent reaction uses light energy from the sun to split water which has been taken in by the organism.Water, when split, gives oxygen, hydrogen, and electrons.These electrons move through structures in chloroplasts and, by chemiosmosis, make ATP.. ask related question comment . Water and light. The first set of reactions of photosynthesis take place in the thylakoid, where chlorophyll and other pigments are located and is called light dependent reactions. The process, known as the Calvin cycle, uses products of the light-dependent reactions (ATP and NADPH) and various enzymes.Therefore, the light-independent reaction cannot happen without the light-dependent reaction. It takes place in chloroplast, on the thylakoid membrane. These involve the reduction of carbon dioxide using reduced NADP and ATP produced in the light-dependent reactions of photosynthesis. The hydrogen ions are used to make ATP. answered by Lifeeasy Authors. In the first stage, light-dependent reactions capture the energy of light and use it to make the energy-storage and transport molecules ATP and NADPH. Ask Question + 100. The light reaction is a light-dependent process which includes a series of events such as light absorption, hydrolysis, the release of oxygen, formation of ATP and NADPH. Which best lists the end products of the light-dependent reactions of photosynthesis? This process will make oxygen and hydrogen ions. For example, plants use sunlight to prepare their food through photosynthesis , which is discussed in this article.
