What substance does photosynthesis produce? | Yahoo …
Prediction: I predict that as the light source (desk lamp) is moved closer to the pondweed (Elodea), the rate of photosynthesis will increase therefore more oxygen will be produced creating more bubbles.
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.
Oxygen is produced as a by-product of photosynthesis.] ..
These results may seem perplexing if we take the adage 'a photon is a photon' to be correct, and the color of light (or more correctly, its energy level) does not make a difference in photosynthesis (which is true.)
Dr. Frank explained the biochemical relation of vitamins and nucleic acids, and specifically used the example of the B-complex vitamins. In metabolizing Vitamin B3 (niacin or niacinamide), for example, the body requires energy for conversions that properly break down the vitamin into its usable components. Thus, cells convert niacin to coenzyme nicotinamide adenine dinucleotide (NAD), which may then be converted to NADP via a phosphate transfer from ATP. The initial reaction involves nicotinic acid with 5-phosphoribosyl 1-pyrophosphate to produce nicotinic mononucleotide (NMN).
He notes that phosphoribosyl pyrophosphate also is the basic compound for purine synthesis (and is formed from ribose-5-phosphate plus ATP). This indicates that the energy of level of a cell plays an essential role in the synthesis of NMN (the precursor of NAD), and therefore that the greater the rate of ATP synthesis, the greater the rate of synthesis of NMN. The next step in the metabolism of niacin involves NMN reacting with ATP to create desamido-NAD, where ATP acts both as a source of energy and a component of the NAD coenzyme.
Ultimately ATP is crucial to the formation of the NAD coenzyme (an important coenzyme in cellular energy metabolism). Thus, Dr. Frank states that higher Krebs cycle activity and oxygen-energy metabolism favors synthesis of NAD, given the availability of niacin (or niacinamide). Moreover, a higher level of niacin (or niacinamide) likewise would favor its own conversion into the active NAD coenzyme. Dr. Frank points to the evident relation of energy metabolism and NAD synthesis, wherein increased nucleic acid and nucleotide intake produces increased energy metabolism and ATP production, which in turn enables both more effective metabolism of niacin and further increases in cellular NAD. He therefore finds a very evident relationship between dietary nucleic acids and NAD with respect to energy production and related metabolism (151).
Dr. Frank relates similar processes for other vitamins (e.g., riboflavin and pantothenic acid) that he finds representative of the B-complex. From his own clinical experience, he relates his observation of definite increases in energy among subjects receiving high-dosage B-complex vitamins (e.g., 50–200 mg of thiamin daily plus other balanced B factors) given with high nucleic acid intake. His clinical observations correspond with his technical analysis of the synergistic biochemical relations between dietary nucleic acids and B vitamins in energy production.
Dr. Frank also discusses other vitamins in his books (e.g., Vitamin A). He concludes: “It is apparent that nucleic acid and nucleotide intake are most importantly related to vitamin usage and function and that the greater the nucleic acid intake, within limits not yet determined, the greater the synthesis and usage of many and perhaps most coenzymes” (153).

Which substance is a product of cellular respiration and …
Yield: The amount of product produced (such as photosynthesis) by the interaction of two substances (such as light and chlorophyll), generally expressed as a percentage. Zooxanthellae typically have a Yield of 0.30 - 0.40, while terrestrial plants' Yields are much higher (~0.80.)
The result of two light reactions is a total of six oxygen molecules (6 O2) released into the air as byproducts and 12 NADPH2 (24 H) carried over to the dark reaction of photosynthesis....

Photosynthesis takes place in only the green parts of plants, which the green part are chlorophyll pigments.
'Light energy' is shown in brackets because it is not a substance
Photosynthetic organisms can be divided into two classes:those which produce oxygen and those which do not. Photosyntheticbacteria do not produce oxygen (in fact some of them calledanaerobes cannot tolerate oxygen) and this is considered a moreprimitive type of photosynthesis (in which the hydrogen donor ishydrogen sulfide, lactate or other compounds, but not water).Plants and one type of bacteria (cyanobacteria) do produceoxygen, an evolutionarily more advanced type of photosynthesis(in which the hydrogen donor is water).
BBC - GCSE Bitesize: Photosynthesis summary
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.
The aim of photosynthesis is to ..
Photoaututrophs utilize sunlight for energy and CO2 for theircarbon source by this process of PHOTOSYNTHESIS whereby sunlightis absorbed by a complex compound known as chlorophyll andconverted to energy which drives a series of chemical reactionsthat ultimately removes hydrogen from water or other compoundsand then combines the hydrogen with carbon dioxide in a way thatproduces sugars.
BioCoach Activity Cell Respiration Introduction
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.
