When does a chemical reaction reaches equilibrium?
equilibrium means the rate of forward reaction = rate of backward reaction... there are three types of equilibrium 1. amount of products > amount of reactants 2. amount of products = amount of reactants 3. amount of products < amount of reactants
What is dark reaction?
Basically, the dark reaction refers to the second stage of photosynthese- the Calvin Cycle, also called the dark reaction or light- independent reaction, because it does not require light energy. During this reaction, molecule of carbon dioxide is joined to RuBP (Ribulose Bisphosphate) by rubisco forming 3- PGA (phosphoglycerid acid). 3-PGA is then rearranged to G3P (three carbon molecule) while oxidizing ATP and NADPH. 2 G3P forms one glucose; one carbon molecule enters the cycle per turn. Since glucose is a 6 carbon sugar, the Calvin cycle have to run a total of 6 times to create oneglucose., using 18 ATP, 12NADPH, and 6 CO2
What are the 3 important events that happen during light reaction?
The three important events that happen during the light reaction of photosynthesis are light absorption by chlorophyll, water splitting to release oxygen, protons, and electrons, and the generation of ATP and NADPH molecules used in the Calvin cycle.
What are the reactions of photosynthesis?
light reaction and dark reaction
What are the raw materials in the dark phase of photosynthesis?
light reaction:-NADP+-ADP-phosphate-waterdark reaction:-enzymes like Rubisco, phosphoglycerate kinase, Glyceraldehyde 3-phosphate, Triose phosphate isomerase, Aldolase and Fructose-1,6-bisphosphatase etc-Ribulose-1,5-bisphosphate (RuBP) a 5 carbon suger which must be recycled-CO2-materials made in light reactions like NADPH and ATPAnd of course chloroplastSource(s):http://en.wikipedia.org/wiki/Calvin_cycle
What are the ending products in the light dependent reaction?
The end products in light dependent reactions are: 1.Oxygen 2.ATP 3.NADPH
What does the light reaction require that the dark reaction does not?
the light reaction requires energy from the sun in the form of photons. these photons excite the electrons in photosystem II and results in the electrons passing through a series of redox reactions (creating a proton gradient that through chemiosmosis turns ADP into ATP) and replaces the missing electrons of photosystem I. then when photons hit photosystem II the electrons are re-energized and go through the reaction to reach NADP+ and though NADP+ reductase are accepted by the newly formed NADPH. so in short the products of the light reaction is what is required by the dark reaction (as well as 3 CO2)
What is the carbohydrate produced by the light independent reaction?
glyceraldehyde-3-phosphates
If 2 grams of substance A reacts with 3 grams of substance B what must be true about the products?
The reaction will form products in a specific ratio based on the stoichiometry of the reaction equation. To determine this ratio, you need to know the balanced chemical equation for the reaction between A and B. The amount of products formed will depend on the limiting reactant in the reaction.
In a chemical reaction a catalyst changes the 1.potential energy of the products 2.potential energy of the reactants 3. heat of reaction 4.activation energy?
A catalyst lowers the activation energy of a reaction, making it easier for the reactants to form products. It does not change the potential energy of the reactants or products, nor does it affect the overall heat of the reaction.
What happens during photosynthesis in the light reaction?
This is the basics to the question: 1. The light reactions occur in the thylakoid membrane. 2. The input to the reaction is light and water. 3. The three products are: ATP, NADPH, and O2. 4. The Oxygen is produced from the water not the Carbon Dioxide. Source: "5 Steps To A 5: AP Biology 2010-2011" by Mark Anestis Comments: This is a great book and is really useful.
When does a chemical reaction reaches equilibrium?

What are the products of the chemical reaction between Cr2O3 and SO3?
The chemical reaction between Cr2O3 and SO3 forms chromium sulfate (Cr2(SO4)3).
What is the reaction that occurs when the products of the light reaction are used to form CC covalent bonds of carbohydrate?
During the Calvin cycle of photosynthesis, the products of the light reactions (ATP and NADPH) are used to convert carbon dioxide into carbohydrates through a series of enzyme-catalyzed reactions. In this process, carbon fixation occurs, where carbon atoms from CO2 are incorporated into a 3-carbon compound (3-phosphoglycerate), which is then converted into glucose and other carbohydrates. This process requires energy from ATP and reducing power from NADPH, produced during the light reactions, to build carbon-carbon (CC) covalent bonds in carbohydrates.
Name 3 products exported by new zealand?

Is the Calvin-Benson cycle the same thing as Cā cycle?
It is called C 3 pathway , or dark reaction or light independent reaction .
What are the 3 products of the light dependent reactions in photosynthesis?
Oxygen, glucose, and ATP
