What are reactants that enter enzyme-controlled reactions?

Reactants that enter enzyme-controlled reactions are typically substrates. Substrates are the specific molecules that enzymes act upon to catalyze a biochemical reaction. The enzyme binds to the substrate at the enzyme's active site, where the reaction takes place.

When a chemical reaction takes place in an open system?

When a chemical reaction takes place in an open system, it can exchange both matter and energy with its surroundings. This means that reactants or products can enter or leave the system, affecting the overall reaction. Consequently, the reaction may not proceed as predicted due to these exchanges.


The which enter into a reaction?

Reactants are the substances that enter into a chemical reaction to form products. They are the starting materials that undergo chemical changes in a reaction.


Elements or compounds that enter into a chemical reaction?

Reactants are the elements or compounds that enter into a chemical reaction. These substances are transformed into different products at the end of the reaction.


What is the smallest unit of a particular element that undergoes chemical change?

The smallest unit of matter that can enter into a chemical reaction is an atom. This is the smallest unit of chemical matter.The smallest unit of matter in all is believed to be a fermion.Matter is made up of molecules, which are made up of various atoms. Atoms are made of neutrons, protons and electrons. Protons and neutrons are made up of both quarks and gluon (think of gluon as the "glue" that holds together quarks). Electrons are made from leptons. Both leptons and quarks are types of fermions.There are some even smaller, theorized, units such as the tachyon-- and the smallest unit of matter might not be a unit at all, but rather a vibration.


The smallest particle of matter which enter a chemical combination?

It is an atom. More specifically, it would be a cation - which is an atom which has "lost" one or more electrons and so is less than an atom.
