Chemical reactions can be produce waste, byproducts, toxic gaz, that can do harm if not well contained.
no chemicals = no life. DNA, proteins, fats, carbohydrates, are all chemicals.

Activation energy of reaction is the same regardless if it is in living organism or in test tube. Yet, the energy of activation can be lowered if catalyst is present. In living things catalyst lower the energy needed for chemical reactions.
No, a chemical reaction is when the atoms are not mixed together but chemical bonded together. You know when a chemical reaction has happened when you can smell, hear or see things reacting.
Chemistry has a few branches that deal with living things such as Biology which is the study of living organisms and others like biochemistry which study the chemical reaction within an organisms.
Reactants are added into the equation to form the chemical reaction. Reactants are substances that are changed into products. Without these reactants, there would be no formula, resulting in no product.
Not necessarily. Things sometimes change colors during a chemical reaction, but a color change is not sufficient evidence of a chemical reaction. You can add drink mix to water and the water turns colors, but it is not a chemical reaction, just a mixture.
A catalysts speeds up the reaction in living things.
enzymes
Enzymes act as catalysts. They speed up the reaction time.
In the 1700s, scientists discovered the chemical and physical basis of living things, and soon they realized that the chemical organization of all living things is remarkably similar. Microorganisms, as forms of living things, conform to this principle and have a chemical basis that underlies their metabolism.

The chemical reaction is caused when things of the environment affect another thing. For example rain dissolves rock over a period of time.

A catalyst. Definition from Pretence Hall Biology: A catalyst is a protein that speeds up the rate of a chemical reaction.
The function of enzymes in living things is to catalyze (instigate, speed up) chemical reactions.
