Only in the presence of light does it produce ATP and H atoms.
A chemical equation is written below which summarizes the reactants and products of the photosynthesis pathway.
The products of the light stage are ATP and NADPH2.
The plant uses the largest molecules to construct cell walls as the plant grows larger.The following equation sums up the photosynthesis reaction:
Sunlight + 6H2O + 6CO2 → C6H12O6 + 6O2In words, this equation states that sunlight, combined with six molecules of water (H2O) and six molecules of carbon dioxide (CO2), produces one molecule of sugar (C6H12O6) and six molecules of oxygen gas (O2).Through this process, green plants capture energy from the sun, use some of it to function and grow, and store some of it in their plant structure, where it’s available to other organisms when they eat the plants.
Priestley concluded that the plants were restoring the air that had been "injured" by the candle or mouse.
History of Photosynthesis Research
In 1779, a Dutch physician named Jan Ingenhousz discovered that submerged willow sprigs produced oxygen gas only in the presence of sunlight.
What Are the Products of Photosynthesis? - ThoughtCo
Plant photosynthesis, both the Light Phase and Dark phasereactions, takes place in chloroplasts, which may be regarded asthe "power plants" of the green leaf cells. At night,when there is no sunlight energy, ATP continues to be generatedfor the plant's needs by respiration, i.e., oxidation of(photosynthetically produced) carbohydrate in mitochondria(similar to animals).
The Z Scheme diagram shows the pathway of an electron fromwater (lower right) to NADP+ (upper left). It also shows theenergy relationships which are measured as voltage potentialshown on the scaleon the right. To raise the energy of theelectrons derived from water (+0.82 volts) to the level necessaryto reduce NADP+ to NADPH (-0.32 volts), each electron must beboosted twice (vertical red arrows) by light energy absorbed inPhotosystems I and II. After each boosting , the energizedelectrons flow "downhill" (diagonal black lines) and inthe process transfer some of their energy to a series ofreactions which ultimately adds a phosporus to ADP to producehigh energy ATP and reduces NADP+ to NADPH. There is analternative shunt whereby the electron flow turns back tocytochrome b563 (green line)and this is called and it occurs when there is no need for NADPH, so onlyATP is produced.
How do we know what the first products of photosynthesis ..
So we can summarize by saying that the photosynthetic plantstrap solar energy to form ATP and NADPH (Light Phase) and thenuse these as the energy source to make carbohydrates and otherbiomolecules from carbon dioxide and water (Dark Phase),simultaneously releasing oxygen in to the atmosphere. Thechemoheterotrophic animals reverse this process by using theoxygen to degrade the energy-rich organic products ofphotosynthesis to CO2 and water in order to generate ATP fortheir own synthesis of biomolecules.
For each electron flowing from water to NADP+ (a net change in1.14 volts), two quanta of light are absorbed, one by eachPhotosystem. Each molecule of oxygen released involves the flowof four electrons from two water molecules to two NADP+s andrequires four quanta of sunlight absorbed by each Photosystem toprovide the energy to do this. These are the "Light PhaseReactions" of photosynthesis, which produce two high energychemical products, namely NADPH and ATP.

4 Answers - What are the main products of photosynthesis?
Water molecules were broken down for their electrons and Hydrogen ions which both aided in the production of ATP.
Know the Products of Photosynthesis.
Water is split in the process, and thus it is the light reactions of photosynthesis that give off 0, as a by-product.
Basic products of photosynthesis - Encyclopedia …
in the formation of glucose and is among the first products of photosynthesis.
are the vital final products of photosynthesis.
The hydrogen ions are then used to produce ATP by a process called Chemiosmosis.
At the end of the electron transport chain, the electrons are picked up, along with hydrogen ions, by a special molecule called NADP which carries them to the dark reaction.
Remember, the purpose of the light reaction was to produce ATP and H atoms for the dark reaction.
vital, products of photosynthesis.
In respiration energy is released fromsugars when electrons associated with hydrogen are transported to oxygen (theelectron acceptor), and water is formed as a byproduct. The mitochondriause the energy released in this oxidation in order to synthesize ATP. Inphotosynthesis, the electron flow is reversed, the water is split (not formed),and the electrons are transferred from the water to CO2 and in theprocess the energy is used to reduce the CO2 into sugar. Inrespiration the energy yield is 686 kcal per mole of glucose oxidized to CO2,while photosynthesis requires 686 kcal of energy to boost the electrons from thewater to their high-energy perches in the reduced sugar -- light provides thisenergy.
Does photosynthesis produce ATP? | Yahoo Answers
Photosynthesis converts these energy- depleted compounds (ADPand NADP+) back to the high energy forms (ATP and NADPH) and theenergy thus produced in this chemical form is utilized to drivethe chemical reactions necessary for synthesis of sugars andother carbon containing compounds (e.g., proteins, fats). Theproduction of high energy ATP and NADPH in plants occurs in whatis known as Light Phase Reactions (Z Scheme) (requiressunlight). The energy releasing reactions which converts themback to energy-depleted ADP and NADP is known as Dark PhaseReactions (Calvin Cycle) (does not require light) in whichthe synthesis of glucose and other carbohydrates occurs.
RE: Does photosynthesis produce ATP
In a broad chemical sense, the opposite of photosynthesis isrespiration. Most of life on this planet (all except in the deepsea vents) depends on the reciprocal photosynthesis-drivenproduction of carbon containing compounds by a series of reducing(adding electrons) chemical reactions carried out by plants andthen the opposite process of oxidative (removing electrons)chemical reactions by animals (and plants, which are capable ofboth photosynthesis and respiration) in which these carboncompounds are broken down to carbon dioxide and water.
ATP & NADPH are products of respiration
Cellular respiration is the process of breaking down food molecules to obtain energy and store it in the form of adenosine triphosphate (ATP) molecules.
Plant cells, after creating sugar molecules through photosynthesis, undergo cellular respiration to create ATP molecules.
