A biochemical reaction is the transformation of one molecule to a different molecule inside a cell. Biochemical reactions are mediated by enzymes, which are biological catalysts that can alter the ...

In a combustion reaction, fuel is burned and reacts with oxygen to release energy. Respiration is the chemical change that takes place inside living cells. Glucose and oxygen are used to release ...

A new technique, based on a chain reaction of recognition and hybridization events between two sets of DNA hairpin molecules, offers an enzyme-free alternative for the rapid detection of specific DNA ...

Thermal means heat. Decomposing is the process of breaking down. Thermal decomposition is a chemical reaction that happens when a compound breaks down when heated. When sodium hydrogencarbonate is ...

Oxygen sensors detect the amount of oxygen in the exhaust. Oxygen sensors usually don’t have a replacement schedule. A bad oxygen sensor can be diagnosed with a code reader or scan tool. A car’s ...

In the United States, about 33 million people and 1 in 13 children have food allergies, and nine foods cause 90% of reactions. These include milk, eggs, peanuts, tree nuts, wheat, soy, fish, shellfish ...
