It sometimes require additional chemical reagents to produce the desired action.
Bacteriostatic methods of action inhibit bacterial growth and reproduction without killing them. Examples include inhibiting protein synthesis, DNA replication, or disrupting cell wall synthesis in bacteria. Antibiotics like tetracycline and macrolides work through bacteriostatic mechanisms.
The three key types of chemical reactions are synthesis (combination), decomposition, and combustion reactions. In synthesis reactions, two or more substances combine to form a single product. Decomposition reactions involve the breakdown of a single compound into two or more simpler substances. Combustion reactions involve the reaction of a substance with oxygen, typically producing heat and light.
The process that changes materials in a rock into new materials is called weathering. Weathering can occur through physical processes such as abrasion and frost action, as well as chemical processes such as oxidation and dissolution. Over time, these processes break down the rock into smaller particles and new minerals may form.
Chemical reactions that form new bonds or break existing bonds between atoms can result in a product with new chemical properties. These reactions can include processes like oxidation, reduction, polymerization, hydrolysis, or substitution, which can lead to changes in the structure and arrangement of atoms in a molecule.
Biological catalysts
Dehydration synthesis is achieved by removing a water molecule to build new molecules, while hydrolysis breaks down molecules by adding a water molecule. In cells, dehydration synthesis is carried out by enzymes that catalyze the formation of new chemical bonds, while hydrolysis is facilitated by enzymes that break down complex molecules into simpler components. Both processes play crucial roles in cellular metabolism and the synthesis and breakdown of biological molecules.
weathering
A chemical change is the result of two or more substances combining to form an entirely new substance. Some synonyms for the term chemical change include synthesis, chemical action, and chemical process.
It sometimes require additional chemical reagents to produce the desired action.
The synthesis of tuberculosis refers to the drug action that is usually performed by the drugs that counter tuberculosis.
The four processes of marine erosion are hydraulic action (pressure from water), abrasion (wearing down of rocks by sediment), attrition (rock particles colliding and breaking down), and corrosion (chemical dissolution of rocks).

A chemical action or reaction is a process that transforms one chemical substance to a new substance.
Mechanical erosion involves physical processes like abrasion by wind, water, or ice that break down rocks into smaller pieces. Chemical erosion includes processes like acid rain or the action of chemicals that dissolve or alter the composition of rocks over time. Both mechanical and chemical processes contribute to the overall weathering of rocks.
