Yes.
Chemical changes are most often reffered to as chemical reactions and are represented by chemical equations.
Most chemical reactions take place in the cytoplasm.
Calvin Cycle
Chemical reactions are a result of valence electron transfer and/or sharing. Valence electrons are located in the outer-most orbitals of the reactant elements. In a sense, though, you could say protons are also involved in chemical reactions. Although an element will never donate, accept, or share protons in a CHEMICAL reaction, they are part of the determination in an elements reactivity. Reactions that do involve protons are termed "nuclear reactions," and are not chemical reactions. In fact, a lot of the methods used to determine chemical reactions -- such as enthalpy -- cannot even be applied to nuclear reactions. Neutrons, like protons are involved in nuclear reactions, but never in chemical reactions. Hope this helps!
Heat energy is directly related to chemical interactions. As heat energy increases, chemical interactions also will due to the increased kinetic energy and therefore interactions of particles.
Heat helps chemical reactions to take place. Light can also cause some chemical reactions to take place.
Any chemical will give off light if it is heated to a sufficiently high temperature. There are also chemicals that give off light at relatively low temperatures. Fireflys produce a type of chemical called luciferins, that produce light.
NADPH
These are generally referred to as polymerization reactions. They may also be called condensation reactions sometimes.
The granules of the inner membrane of the mitochondrion are believed to be the site of chemical reactions that produce the electron transport system that generates a proton gradient. Also site of the ATPase complex which uses the proton gradient to produce ATP.
It cannot occur in the dark. It contains an enzyme called rubisco which is a light-activated enzyme. Also the Calvin cycle uses the chemical energy produced in the light reactions, and the light reactions need sunlight energy in order to produce the energy needed in the Calvin cycle. Hope that helps :)

Enzymes speed up the chemical reactions by forcing the reactant molecules into their correct orientation. The enzymes also lower the required energy for collision to produce a reaction.
Create products for which the light-independent reaction is able to use to continue the rest of photosynthesis.
The main purpose of the light independent reaction is to produce glucose.
The Calvin cycle does not require light, these reactions are also called the Light Independent reactions.
Light can indeed cause chemical reactions. A very good example of this happens constantly above our heads. The light from the sun causes the formation of oxygen radicals in the atmosphere by disocciation. The formula for this is: O2 + hv --> 2O. , where h is planck's constant and v is the frequency of the light. The "." on the oxygen atoms formed represent a single unpaired electron which causes them to become very reactive (they will react with almost anything). They react with other O2 molecules to form O3, better known as ozone. This is how the ozone layer is formed. Reactions can indeed produce light. Ever used a glowstick? You break a capsule inside and then shake the stick to cause a chemical reaction which gives off light. This also explains why glowsticks stop glowing. The reaction has finished. Unfortunately I do not know the reaction for this process or indeed which chemicals are involved.
