Term | Definition |
---|---|
metabolic respiration | reactions and processes in molecules in our cells to release energy |
exothermic reaction | the products have less energy than the reactants |
catalyst | A substance that lowers the activation energy of a chemical reaction, greatly increasing its reaction rate. |
metabolism | all of the chemical reactions that occur within a living cell |
activation energy | The energy it takes to form an intermediate when reactants become products. It is the energy supplied by kindling wood when you are trying to start a camp fire. A catalyst lowers the activation energy, making the reaction go faster. |
enzymes | Proteins that catalyze chemical reactions |
