it lowers the amout of activation energy needed to start the reaction.
Enzymes are unchanged during chemical reactions as they act as catalysts and do not participate in the reaction itself. Enzymes are reusable as they can catalyze multiple reactions without being consumed in the process.
An enzyme
it is broken down to fuel chemical reactions & is created by chemical reactions.
A catalyst lowers the activation energy without being consumed during a reaction
This a normal product in many chemical reactions.
Enzymes are not destroyed during chemical reactions.
Enzymes reduce the activation energy of a reaction. They accomplish this feat by altering the local chemical environment of the substrates while typically bringing the reactants into close proximity and even stabilizing conformers that promote reaction.
Catalysts doesn't undergo a chemical change during a chemical reaction.
Catalysts can increase the rate of a chemical reaction by lowering the activation energy required for the reaction to occur. They can also change the reaction pathway, leading to different products being formed. Additionally, catalysts are not consumed during the reaction and can be used multiple times.
During the process of breaking down food to get energy, chemical reactions such as catabolic reactions occur. These reactions involve the breakdown of complex molecules into simpler ones, releasing energy in the process. Key catabolic reactions include glycolysis, the citric acid cycle, and oxidative phosphorylation.
A catalyst doesn't undergo a chemical change during a chemical reaction.
Energy is necessary for chemical reactions because it allows molecules to overcome activation energy barriers and initiate reactions. Common sources of energy for chemical reactions include heat, light, electricity, and catalysts. These sources provide the necessary energy to break existing bonds and form new ones during a chemical reaction.
