Light-independent reactions The light-independent reactions of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma, the fluid-filled area of a chloroplast outside of the thylakoid membranes.These reactions take the products (ATP and NADPH) of light-dependent reactions and perform further chemical processes on them.n the first stage of the Calvin cycle, a CO 2 molecule is incorporated into one of two three-carbon molecules (glyceraldehyde 3-phosphate or G3P), where it uses up two molecules of ATP and two molecules of NADPH, which had been produced in the light-dependent stage.

Photosynthesis uses energy from sunlight to synthesise organic molecules from inorganic sources The light dependent reaction takes place in the chloroplast and is important to produce ATP and NADPH + H+. Both molecules and carbon dioxide (CO2) are needed in the light independent reaction (Calvin Cycle) to produce a hexose sugar, such as glucose, from RuBP. Glucose is used to in the mitochondrion to produce the energy molecule ATP. NAD+ is also needed for respiration, but is not produced by photosynthesis.

Light-independent reactions This process happens when light is available independent of the kind of photosynthesis (C3 carbon fixation, C4 carbon fixation, and Crassulacean Acid Metabolism); CAM plants store malic acid in their vacuoles every night and release it by day in order to make this process work.

Overall Process of Photosynthesis Overall Process of Photosynthesis. The best‐understood reaction for the synthesis of glucose, and probably the most important quantitatively, is photosynthesis. Photosynthesis converts carbon from carbon dioxide to glucose with reducing equivalents supplied from water and energy supplied from light. The energy in light is dependent on its wavelength, and is given by the following relationship. The Greek letter nu, ν, stands for the frequency of the light, h is a constant called Planck’s constant, c is the speed of light, and λ is the wavelength. In other words, the energy of light is inversely proportional to its wavelength. The longer the wavelength, the less energy it contains.

Which is most closely associated with the Calvin cycle? Best Answer: It's the light-independent reaction involved in photosynthesis. It uses ATP molecules and NADPH molecules to convert carbon dioxide into glucose(a simple sugar). It is also known as the Calvin-Benson(the two scientists that discovered it) Cycle or simply as the light-independent reaction in photosynthesis. The ATP and the NADPH comes from the light-dependent reactions in photosynthesis, which turns water into oxygen. Source(s): ATP-Boy · 8 years ago.

Photosynthesis: The Light Reaction and Products Simplified The production of carbohydrates at the end of photosynthesis is not a simple process and occurs in 2 different stages known as the Dark and Light Reaction. The Light Reaction of photosynthesis should be properly called the Light Dependent Reaction because this is the only stage that captures energy in light. The dark reaction, also known as the Light Independent Reaction, functions independently of light and cannot capture energy.

2.06 The light-dependent reactions convert light energy into chemical energy. This chemical energy is then used in the light-independent reactions to fix carbon dioxide into organic molecules. In photosynthetic eukaryotes such as plants and algae, photosynthesis occurs in specialized structures called chloroplasts.

Photosynthesis Water, when broken, makes oxygen, hydrogen, and electrons. Hydrogen, along with electrons energized by light, convert NADP into NADPH which is then used in the light-independent reactions. Oxygen diffuses out of the plant as a waste product of photosynthesis and ATP is synthesized from ADP and inorganic phosphate. This all happens in the grana of chloroplasts.

- The light reactions are the steps of photosynthesis that convert solar energy to chemical energy. Light absorbed by chlorophyll drives a transfer of electrons and hydrogen from water to an acceptor called NADP+ (nicotin-amide adenine dinucleotide phosphate), which temporarily stores the energized electrons.

Light-dependent reactions In photosynthesis, the light-dependent reactions take place on the thylakoid membranes. The inside of the thylakoid membrane is called the lumen, and outside the thylakoid membrane is the stroma, where the light-independent reactions take place. The thylakoid membrane contains some integral membrane protein complexes that catalyze the light reactions. There are four major protein complexes in the thylakoid membrane: Photosystem II (PSII), Cytochrome b6f complex, Photosystem I (PSI), and ATP synthase.

10/14/2016 Light-independent reactions (also called dark reactions): ATP and NADPH are rich energy sources, which drive dark reactions. During this process carbon dioxide and water combine to form carbohydrates like glucose. This is known as carbon fixation. Photosynthesis in the future. Photosynthesis generates all the breathable oxygen in the atmosphere, and renders plants rich in nutrients. But researchers have been looking at ways to further harness the power of the process.

Cells and Cell Processes Soils. Light and dark reactions in photosynthesis. Photosynthesis is divided in two parts: 1. Light-dependent reactions (light reactions). 2. Light-independent reactions (dark reactions). Light reactions need light to produce organic energy molecules (ATP and NADPH). They are initiated by colored pigments, mainly green colored chlorophylls. Dark reactions make use of these organic energy molecules (ATP and NADPH). This reaction cycle is also called Calvin Benison Cycle, and it occurs in the stroma. ATP provides the energy, while NADPH provides the electrons required to fix the CO2(carbon dioxide) into carbohydrates.
