it's react towards light. it transforms light energy to a chemical energy of photosynthesis. So this light energy is trapped by chlorophyll molecules and converted to chemical energy. dB!

What does the chloroplast do in the plant cell?
accepts photons from the sun. uses the quantanized energy to produce ATP. So basically, it feeds the plant.
What is produced in chloroplasts?
As a energy source, the chloroplast produces starch during the light independent reaction of photosynthesis. Starch is a carbohydrate that is used in plants as energy the same way it is for humans.
How does enzymes speed up chemical reactions?
The way enzymes speed up chemical/biochemical reactions is the same way that catalysts work. They provide an alternate pathway for the reaction which has a LOWER activation energy. They don't actually decrease the activation energy of the pathway in question, but rather they provide a different pathway that has a lower energy of activation.
What are two advantages of the presence of coupled reactions?
A coupled reaction is a chemical reaction having a common intermediate in which energy is transferred from one side of the reaction to the other. Many things are made this way.
How is most energy produced?
Most energy is produced by the breaking and reforming of molecular bonds. A car's combustion reaction in which fuel is converted into energy, co2 and water is a good example of this. Energy is rarely produced on the atomic level, such as a nuclear power plant or an atom bomb. Energy is produced this way through Einstein's E=mc^2. In an atomic reaction the mass of the products is slightly less then the mass of the reactants. Plug the change in mass into Einstein's equation and you get a lot of energy. To recap, most energy is made on the molecular level with endothermic (reactions which absorb energy) and exothermic reactions (reactions which emit energy), however a small amount takes place on the atomic level.

Why don't animal cell have a chloroplast How do they make energy?
Because they would turn green, they're plants! They make energy the same way humans do.
How can nuclear energy be changed to mechanical energy?
One way it to allow the heat from controlled nuclear reactions to boil water. The steam can then power steam turbines in much the same way that steam from coal or wood fired boilers can be used. In the simplest terms this is how most if not all nuclear power plants work.
What are the chemical changes of electriciy?
CHEMICAL Chemical energy is stored in the bonds between atoms. This stored energy is released and absorbed when bonds are broken and new bonds are formed - chemical reactions. Chemical reactions change the way atoms are arranged. These reactions both absorb and release energy, but the net reaction releases energy.
What is one way that the potential energy in wood can be changed into another form of energy?
The most obvious way would be to burn it.
What is the role of ATP as an intermediate between catabolism and anabolism?
Catabolic reactions are exothermic and anabolic reactions are endothermic. For endothermic reactions ATP supplies the energy by its hydrolysis to ADP and inorganic phosphate, which can be recycled to ATP by utilizing the energy produced by exothermic reactions. By this way ATP serves as an intermediate linking the catabolism and anabolism.
What is one way sunlight is changed into electric energy?
well, sunlight can be turned in to solar energy and that can be turned into electric.

As a energy source, the chloroplast produces starch during the light independent reaction of photosynthesis. Starch is a carbohydrate that is used in plants as energy the same way it is for humans.

Which is one way the body uses carbohydrates?
To speed up reactions
Endothermic and exothermic reaction?
An exothermic reaction releases energy, usually to the surroundings. There is a net loss of energy from the reactants. However, exothermic reactions also need a little energy to get started, but this is less than the eventual amount given out. An endothermic reaction takes in energy, also usually from the surroundings. There is a net gain of energy into the reactions. Again, a little energy is lost, but this is hardly anything compared to the amount taken in.
Describe two ways to release biomass energy?
Two ways to relase biomass energy is to burn biomass energy that is the most common way. Another way is, biomass can also be changed into liquid fuel.
