Chapter 7 Chemical Reactions

substance that speeds up a chemical reaction but is not used up itself or permanently changed.

• enzyme

• catalyst

• activation energy

• chemical reaction

shorthand form for writing what reactants are used and what products are formed in a chemical reaction; sometimes shows whether energy is produced or absorbed.

• product

• rate of reaction

• Chemical equation

• reactant

process that produces chemical change, resulting in new substances that have properties different from those of the original substances.

• Chemical equation

• Endothermic reaction

• Exothermic reaction

• Chemical reaction

chemical reaction in which heat energy is absorbed.

• exothermic reaction

• endothermic reaction

• chemical reaction

• inhibitor

catalysts that are large protein molecules which speed up reactions needed for your cells to work properly.

• rate of reaction

• inhibitor

• enzyme

• catalyst

chemical reaction in which heat energy is released.
