The answer to this dilemma is catalysts—also referred to as enzymes. Many of these enzymes are made in human cells because human DNA carries the directions to make them. … WebThe collision theory states that chemical reactions can occur when atoms, ions, and molecules collide. Activation energy is needed to disrupt electronic configurations. Reaction rate is the frequency of collisions with enough energy to bring about a reaction Reaction rate can be increased by enzymes or by increasing temperature or pressure 7.

WebCatalase is an enzyme which is found in most living organisms. It catalyses the decomposition of hydrogen peroxide into water and oxygen. 2H 2 O 2 + Catalase >>> 2H 2 O + O 2. Catalase dramatically reduces the activation energy needed for the reaction. Without catalase, the decomposition would take much longer and would not be fast …

WebAn enzyme's activity tells you how well an enzyme performs its function and how fast the reaction takes place.
