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.
What else can I help you with?
What is the aim of electrolysis?
The aim of electrolysis is to use an electric current to bring about a non-spontaneous chemical reaction, typically to separate compounds into their constituent elements or to produce desired products through redox reactions at the electrodes.
What substance acts like a carrier molecule that facilitate chemical reactions?
Enzymes act as carrier molecules that facilitate chemical reactions by lowering the activation energy required for reactions to occur. They bind to specific substrates and help to bring them together in the correct orientation and environment for the reaction to take place. This allows the reaction to proceed at a faster rate than it would without the enzyme.
Are enzymes involved in synthesis reactions only?
No, enzymes can also be involved in breakdown reactions. Enzymes can catalyze both synthesis (anabolic) and breakdown (catabolic) reactions in the body, depending on the specific enzymatic reaction and the needs of the cell or organism.
What does neutalize mean?
"Neutralize" means to render something ineffective or harmless, typically by opposing or counteracting its effects. This can refer to anything from neutralizing a chemical reaction to neutralizing a threat or danger.
Why is catalytic activity of enzymes essential to ensure and regulate cellular metabolism?
Enzymes lower the activation energy for chemical reactions, allowing the reactions to proceed. Enzymes also can serve to bring components of a reaction together in the proper orientation. Enzymes can hydrolyze macromolecules into smaller components, enabling them to be transported across the cell membrane. Without enzymes, many metabolic reactions would not be able to be conducted efficiently, if at all.

Why are enzymes important to cell?
They help bring about chemical reactions.
What occurs during a chemical reaction?
the element
What is a chemical reagent?
Reagent bottle is a bottle designed to contain chemical reagents. Bottles are made generally from glass, plastic coated glass, polyethylene. The volumes are extremely variable, from 1 mL to liters.
Are enzymes involved in synthesis reactions only?
No, enzymes can also be involved in breakdown reactions. Enzymes can catalyze both synthesis (anabolic) and breakdown (catabolic) reactions in the body, depending on the specific enzymatic reaction and the needs of the cell or organism.
What is an agent that causes or speeds up a reaction without permanently altering itself?
Catalysts speed up chemical reactions without being used up or damaged in the process. Catalysts provide an active site that helps to bring chemicals together and thus increase the likelihood of a reaction taking place (and thus speeding up the reaction).As well as speeding up reactions catalysts also reduce the activation energy needed for reactions to take place.Enzymes are biological catalysts made out of protein.All catalysts can be damaged or inhibited by either changing the shape of the active site or blocking it altogether.
What is another word for reagent?
Another word for reagent is reactant or compound. Reagents are substances used in chemical reactions to bring about a chemical change.
What is the name of a chemical that reacts with another chemical?
A chemical that reacts with another chemical is called a reagent. Reagents are substances used in chemical reactions to bring about a transformation or to detect the presence of other substances.
What does neutalize mean?
"Neutralize" means to render something ineffective or harmless, typically by opposing or counteracting its effects. This can refer to anything from neutralizing a chemical reaction to neutralizing a threat or danger.
Is mixing bases and acids bad?
Yes, mixing bases and acids can be dangerous as they neutralize each other in a chemical reaction that can release heat, gases, or even explode in some cases. It is important to avoid mixing them unless you are following a specific procedure in a controlled setting.
