How is order of reaction determined graphically?
in our syllabus there is only the first and the zero order reaction in which if the graph is plotted between the concentration and time then it is a zero order reaction while if the graph is between the log of concentration and time then the reaction is of the first order.hope this will help u.
What are products reactants and catalysts?
* Reactants: the initial compounds in a chemical reaction. * Products: the final compounds in a chemical reaction. * Catalyst: a chemical compound which help the chemical reaction but not react with the other compounds.
For which of reaction listed below will gibbs free energy always be positive?
Guys watch out the question, if your question end with positive then the answer will be An endothermic reaction that decreases in entropy. If the question end with negative then its An exothermic reaction that increases in entropy--APEX hope this help
What happens to the atoms within molecules undergoing a chemical reaction?
In a chemical reaction sometimes old bonds are broken and new bonds are formed.
What is it when a compound breaks apart into separate substance?
It's called Decomposition. For example, 2KClO3 --> 2KCl + 3O2
How do the reaction help the Calvin cycle?
Light reactions produce NADPH and ATP, which are used during the Calvin cycle.
Why doesn't Calvin cycle occur at night?
Obviously, there is no sunlight energy for light dependent reactions to occur while calvin cycle AKA light independent phase does not require light as it uses energy in the form of ATP and the NADPH to form sugars
What are the reactants and products of light-dependent reaction?
kk so first u must understand tht the Light reaction and the calvin cycle r totally differentthe light reaction aka the light dependent reaction depends on light, this reaction takes place in the stroma, in the chloroplast. U can research more about how it exactly works but basically the products of it is ATP and NADPH2. These products u get them after the light from the sun goes through cyclic or non cyclic reaction. ADP + Pi = ATP and NADPH+ + H+ = NADPH2Then photosynthesis continues, the next step is carbon fixation. Carbon fixation is still part of the light dependent reaction. After the carbon gets fixed it enters the Calvin cycle.the calvin cycle is now part of the dark reaction aka the light independent reactions, and like the name says it does not depend on light energy. The calvin cycle takes place in the thylakoid, which is in the chloroplast.Here is goes through a series of steps in which enzymes to different stuff to it to get the CO2 into an organic molecule..The main enzyme is called Rubisco (which is a short form for Ribulose biphosphate carboxylase/oxygenase). the calvin cycle produces glucose, but u need 6 turns of the calvin cycle for every molecule of glucose. the calvin cycle also produces carbohydrates, like lipids.Glucose is energy for the body, it can be broken down to get ATP, by a process called glycolysisfurthermore, there are other things tht happen in between these steps tht help photosynthesis continue, such as hydrolysis and chemiosmosis to produce more ATP through a concentration gradient and ATP synthataze. u must take into account tht these processes are very complex and the description above is only a brief overview, im not sure wut grade ur in n how much u need to kno. so with the names of it u can look it up
Summarize what happens during the Calvin cycle?
Is used to creat NADPH+ to carry energy to other parts of the chloroplast Is used to create some ATP from ADP Is udes to breakup water into protons, electrons, and oxygen atoms (with help from enzymes) Hope that helped (:
What is the relationship between the light dependent reaction and Calvin cycle?
The two reactions of photosynthesis are connected by two substances: ATP and NADPH. These are produced by the light dependent reaction and are used by the light independent reaction. ATP is produced from ADP and Pi (phosphate): ADP + Pi ---> ATP This reaction requires energy to make it work, and this energy comes from light absorbed in the light dependent reaction. NADPH is produced from NADP+ and H: NADP+ + H ---> NADPH This reaction also requires energy, which is obtained from light in the light dependent reaction. The ATP and the NADPH are used in the light dependent reaction to provide energy and a source of H to convert CO2 to CH2O (carbohydrate). The products of the reactions (ADP, Pi, NADP+) are recycled in the light dependent reaction to produce more ATP and NADPH.

Photosynthesis can be divided into two parts what are they?
Light Reaction and Calvin Cycle
What happens during light independent stage of photosynthesis?
In the light-dependent stage, plant cells absorb light energy through proteins containing pigments, such as chlorophyll. In the final part of the stage, the process called photophosphorylation turns ADP into ATP, using the light energy taken in to make these high-energy molecules. ATP and NADPH are used in the Calvin cycle, which is called a "light-independent" stage, to remove carbon from carbon dioxide to use in creating glucose and other molecules.
How does chorophyll help a plant?
Chlorophyll is what traps light energy in order for the plant to produce energy (ATP and NADPH) to be used in the Calvin cycle. Chlorophyll is found within the chloroplasts in clusters known as the antennae complex. the light excites an electron within the antennae complex and the electron is passed down energetically favorable chlorophyll molecules until it reaches what is called the reaction center. This is where the electron can do work in producing the energy... but I wont ramble on about that.
What helps combine water and carbon dioxide in the leaves?
Technically water and carbon dioxide don't combine. The water is brought to the leaf by a vein and makes its way to the Thylakoid space of a Thylakoid (green sacks in the stroma) in the Chloroplast. The water molecule is then split into two hydrogen ions and an oxygen atom (later combined with another oxygen atom to form o2). The electrons taken from the hydrogen atoms flow through the Light Reaction stage of photosynthesis until picked up by a electron carrier. Carbon dioxide enters the leaf through pores and is used in the Calvin Cycle of photosynthesis which takes place in the stroma (inner membrane fluid) of the Chloroplast. Electrons taken from water molecules in the Light Reaction stage are now used in the Calvin Cycle with carbon dioxide to help produce glucose.
What is light-depent reaction in photosynthesis?
It means that for a reaction (usually chemical) to take place, light is needed. An example of this can be seen in photosynthesis.
Where does the dark reaction take place?
It takes place in the stoma
By which enzyme is carbon first fixed in C4 photosynthesis?
With the help of the enzyme RuBisCo this reaction takes place. CO2 + ribulose biphosphate ( a 5 C sugar ) -> 2(3-phosphoglycerate)( 3 C sugar) This happens in the Calvin cycle. With CO2 and RuBP a reaction takes place with ATP and NADPH to do a complicated bit of arranging with the three CO2's coming into the cycle. Six of the 3-phosphogylcerates are made, but only one the product of one cycle and the rest go back into the cycle. The 3 carbon sugar then can be used to build glucose or used in the mitochondria for energy.
