Light-Independent Reactions of Photosynthesis For the sake of consistency with most textbooks and for ease of stoichiometry (making the numbers of atoms add up), we shall skip this and continue to state glucose as the end product. So far (in the light-dependent reactions) however, we have only produced ATP and NADPH. The subsequent reactions leading to the formation of glucose do not directly involve the harnessing of light energy (that has already been done to produce ATP and NADPH), and are therefore called light-independent.

Section 16.3 Photosynthetic Stages and Light-Absorbing Pigments The reactions that generate the ATP and NADPH used in carbon fixation are directly dependent on light energy; thus stages 1 – 3 are called the light reactions of photosynthesis. The reactions in stage 4 are indirectly dependent on light energy; they are sometimes called the dark reactions of photosynthesis because they can occur in the dark, utilizing the supplies of ATP and NADPH generated by light energy.

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-independent reactions It is one of the light-independent reactions used for carbon fixation. Photosynthesis occurs in two stages in a cell. 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.

Light-independent reactions It is one of the light-independent reactions used for carbon fixation. Photosynthesis occurs in two stages in a cell. 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.here are three phases to the light-independent reactions, collectively called the Calvin cycle: carbon fixation, reduction reactions, and ribulose 1,5-bisphosphate (RuBP) regeneration. Despite its name, this process occurs only when light is available. Plants do not carry out the Calvin cycle by night.

The light-dependent reactions of photosynthesis The light-dependent reactions take place in the membranous sections of the chloroplast - thylakoids (granae/lamellae) - which offer a large surface area to absorb light energy. Do not confuse NADP with NAD which is a similar molecule involved in respiration. The main function of these reactions is to provide a source of ATP and reduced NADP, which are used to reduce CO2 in the light independent reactions. There are two photosystems consisting of chlorophyll and associated molecules.

Light-independent reaction 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.

Describe the two main sets of reactions (biochemical pathways) of photosynthesis.? Best Answer: STAGE 1 - CALLED THE LIGHT REACTIONS OR LIGHT DEPENDENT REACTIONS. Energy is Capture from Sunlight. Water is Split into Hydrogen Ions, Electrons, and Oxygen (O2). The O2 Diffuses out of the Chloroplasts (Byproduct). The Light Energy is Converted to Chemical Energy, which is Temporarily Stored in ATP and NADPH.

Critical Thinking Questions The products of the light dependent reaction are used to power the Calvin cycle to produce glucose. When photons strike photosystem (PS) II, pigments pass the light energy to chlorophyll molecules that in turn excite electrons, which are then passed to the electron transport chain.

The Light-Dependent and Light-Independent Reactions The light reactions, or the light-dependent reactions, are up first. We call them either and both names. The whole process looks a little like this: Do not freak out or fill your head with all the complicated names in that diagram. No—stop right there. All in all, the process is simpler than it looks.

- 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-Independent Reactions of Photosynthesis Additionally, the cycle involves the reduction of 9 ATP (18 per glucose) and 6 NADPH (12 per glucose) which are provided, as we have already seen, by the light-dependent reactions: this is where the 6H 2 O on the reactants side, and the 6O 2 on the products side, of our simplified photosynthesis equation come in.

Photosynthesis The light-dependent reactions. When light energy is absorbed by a chlorophyll molecule its electrons gain energy and move to higher energy levels in the molecule (photoexcitation). Sufficient energy ionises the molecule, with the electron being 'freed' leaving a positively charged chlorophyll ion.

Why do light-dependent and light-independent reactions take place only in the light? However, it needs the products of the light-dependent reaction (ATP and NADPH), so it cannot continue indefinitely without it. In the light-independent reaction, the ATP and NADPH produced by the light-dependent reaction are used to convert carbon dioxide into carbohydrate, e.g., glucose.This happens in a series or reactions called the Calvin cycle. A link is provided.owever, it needs the products of the light-dependent reaction (ATP and NADPH), so it cannot continue indefinitely without it.

Light-independent reactions 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 Dependant Reactions You are here. Light Dependant Reactions. The first reactions of photosynthesis require light energy, and are called light dependant reactions. The aim is to produce ATP from ADP and inorganic P and harvest hydrogen so that carbon dioxide can be reduced to form a carbohydrate in the second series of reactions. The production of ATP using light is called photophosphorylation.

- 1. Light Dependent Reactions (LDR) - Needs light to occur. Makes ATP, NADPH, O2. 2. Light Independent Reactions (LIR) - May occur in light or dark. Converts CO2 to sugars. The ATP & NADPH accumulate & diffuse to the stroma where they are used to make sugar. ATP is a short-term energy carrier & main energy source for all cells.

- 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.he thylakoid membrane contains some integral membrane protein complexes that catalyze the light reactions.
