- 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. 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.

Light-Dependent Reactions of Photosynthesis Light-Dependent Reactions of Photosynthesis. The first major set of processes in photosynthesis, in which light energy is initially converted into chemical energy as ATP and NADPH, takes place across the chloroplast thylakoid membranes, between the chloroplast stroma and the thylakoid space.

Light-dependent reactions Light-dependent reactions of photosynthesis at the thylakoid membrane In photosynthesis, the light-dependent reaction takes 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.

Microbial Metabolism Light Dependent Reactions. Photosynthesis is usually divided into two sets of reactions, light dependent and light independent. As you might expect, the light dependent reactions depend on light; this is where the plant converts light energy to chemical energy in the form of ATP and electrons.

- Calvin cycle 3. Products of the Calvin cycle The immediate products of one turn of the Calvin cycle are 2 glyceraldehyde-3-phosphate (G3P) molecules, 3 ADP,and 2 NADP + (ADP and NADP + are regenerated in the Light-dependent reactions). Each G3P molecule is composedof 3 carbons.

- Light and dark reactions in photosynthesis Photosynthesis is divided into 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.

- 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.

- The light reactions can be split into the following specific steps: 1  1. Light absorption & splitting of water. 2  3. Movement of electrons through electron acceptors to power a hydrogen pump. 3  4. Re-energizing electrons so they can produce NADPH.

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.

Photochemistry The first law of photochemistry, known as the Grotthuss–Draper law (for chemists Theodor Grotthuss and John W. Draper), states that light must be absorbed by a chemical substance in order for a photochemical reaction to take place.

- Quick Answer. The reactants of photosynthesis are water, light and carbon dioxide, while the products are oxygen and sugars. Cellular respiration occurs in direct synchronicity with this process, using the products of photosynthesis as its reactants and producing its reactants. Continue Reading.

What Are the Reactants & Products in the Equation for Photosynthesis? These products of the light reaction are then used by the plant during the second stage of the photosynthesis process. Light-Independent Process. The second stage of the photosynthesis process is the light-independent process, or dark reactions. During this stage, the ATP and NADPH are used to break chemical bonds and form new ones.

Light-dependent reactions The reaction center is in the thylakoid membrane. It transfers light energy to a dimer of chlorophyll pigment molecules near the periplasmic (or thylakoid lumen) side of the membrane. This dimer is called a special pair because of its fundamental role in photosynthesis.

- The light-independent reactions are sometimes called the Calvin cycle because of the cyclical nature of the process. 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 light-independent molecules depend on the energy carrier molecules, ATP and NADPH, to drive the construction of new carbohydrate molecules.

Introduction As it turns out, some of the light energy absorbed by pigments in leaves is converted to a different form: chemical energy. Light energy is converted to chemical energy during the first stage of photosynthesis, which involves a series of chemical reactions known as the light-dependent reactions. In this article, we'll explore the light-dependent reactions as they take place during photosynthesis in plants.

Light-dependent reaction depends on light and converts light energy to chemical energy stored in bonds of 2 molecules, ATP and NADPH. 1. The light-independent reaction used ATP and NADPH from light-dependent reaction to assemble sugars. This reaction can occur in light and dark.
