They are called Enzymes
A catalyst. It does do by decreasing the energy required for the reaction to take place (activation energy).
an enzyme
Catalysts speed up reactions and they do this by decreasing the activation energy. The way they decrease the activation energy is by providing an alternate pathway for the reaction. Because there are so many different reaction mechanisms/pathways in chemistry, there must be many different catalysts.
Enzymes are biologic catalyst that speed up chemical reactions by lowering its activation energy Ea
It is true that a catalyst is used in chemical reactions to help speed up the reaction by reducing activation energy.
A catalyst lowers the activation energy without being consumed during a reaction
No, not all biochemical reactions require a catalyst. However, catalysts can help accelerate the rate of biochemical reactions by lowering the activation energy required for the reaction to proceed.
Catalysts doesn't affect the energy of reactions
A catalyst changes the reaction mechanism to one with a lower activation energy; activation energy is lowered when a catalyst is added
Activation energy is the energy required by a reaction for the reaction to occur. The catalyst lowers the activation energy, making it easier for the reaction to happen.Improvement:A catalyst don't lowers the activation energy. A catalyst creates a alternative route (*) for the same reaction with a lower activation energy.* = as a result of the interaction of the reagents with the catalyst.
catalyst will generally reduce the activation energy
A catalyst increases the reverse rate of the reaction
