catalyst
An enzyme works to speed up chemical reactions in a living organism.
The average rate of disappearance for a substance in a chemical reaction is the speed at which the substance is used up over time. It is calculated by dividing the change in concentration of the substance by the change in time.
A catalyst alters (usually increases) the speed of a chemical reaction in which there is no net change in the amount of catalyst present after reaction is complete.
A catalyst is a substance which alters the rate of a chemical reaction but is chemically unchanged at the end of the reaction. basically it increases or decreases the speed of a chemical or biological reaction, but it does not get itself involved in the reaction. hoped this helped (:
Ensymes speed up a chemical reaction by acting as organic catalyst, a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.

The rate of disappearance equation is used to calculate how quickly a substance is used up or changed in a chemical reaction. It helps determine the speed at which the reaction is happening.
these are chemicals that speed up chemical reactions?
The rate of disappearance formula is used to calculate the speed at which a substance is consumed or transformed in a chemical reaction. It is typically expressed as the change in concentration of the reactant over time.
A catalyst alters (usually increases) the speed of a chemical reaction in which there is no net change in the amount of catalyst present after reaction is complete.
