Enzymes work by lowering the what?
Also known as activation energy. threshold energy or you can also say enzymes lower the energy barrier
How does an enzyme catalyze a chemical reaction in regards to activation energy?
Any catalyst will make a chemical reaction easier or quicker to happen by lowering the activation energy. On a energy diagram, you will see a lower "hill" for activation energy, which corresponds to less energy required to begin the reaction.
Describe the roles of a catalyst and substrate in a chemical reaction?
A catalyst is a substance that speeds up the rate of a chemical reaction. Catalysts work by lowering a reaction's activation energy.A substrate is a reactant of an enzyme-catalyzed reaction.
How does the additions of a catalyst affect the energy of activation of a chemical reaction?
A catalyst changes the reaction mechanism to one with a lower activation energy; activation energy is lowered when a catalyst is added
What is a catalyst?
A catalyst is a substance that speeds up a given chemical reaction by lowering its activation energy without itself being used up.
How does an enzyme help in a chemical reaction?
It speeds up the reaction by lowering activation energy.
How an enzyme helps to speed up chemical reaction?
by lowering the activation energy

Function of a enzyme?
An enzyme speeds up a chemical reaction by lowering the activation energy.
What is the protein that speeds up chemical reactions by lowering the activation energy in the reaction?
Enzyme's
Can enzymes increase the rate of chemical reaction by lowering activation energy barriers?
That's the way they do it
Enzymes speed up chemical reactions by?
by lowering the activation energy of reactions
Which group of biological molecules can speed up chemical reactions by lowering a reaction's activation energy?
Enzymes

What can alter the activation energy if a reaction?
A catalyst alter rate of reaction by lowering the activation
