Enzymes speed up a reaction by lowering the activation energy. This is the amount of energy required to start the reaction. By lowering the activation energy, the reaction can proceed much more quickly.
to speed up a chemical reaction
Enzyme or catalyst
speed up chemical reaction because of the lowered activation energy
This would be an enzyme.
The reaction will speed up.
the reaction will speed up
by lowering the activation energy
By adding more substance that the enzyme is acting upon, it forces that enzyme to be faster in order to complete the process.
A specific enzyme is an enzyme that only changes the speed of ONE reaction. (It only acts on one particular substance that happens to be compatible with that enzyme) i.e. if enzyme A is specific to reaction A, it will change the speed of reaction A. However it will have no effect on any other reaction like reaction B or C.
3 factors that affect the speed of an enzyme catalysed reaction are: .Temperature .Enzyme Concentartion .Substrate concentration
An enzyme works to speed up chemical reactions in a living organism.
An enzyme is a catalyst that speeds up a chemical reaction. It functions by lowering the activation energy required for a reaction to occur, and by reducing the activation energy, the reaction speeds up.
