Kinetic Energy
Energy at work or in motion
Potential Energy
Stored energy
Thermal Energy
Heat energy. Energy lost in the form of heat is not recoverable.
Chemical Energy
Potential energy stored in chemical bonds.
Autotrophs
Producers that make their own food, typically from photosynthesis. Can also do cellular respiration.
Heterotrophs
Consumers that eat other food, and can do cellular respiration.
Anabolic
Creating chemical bonds and storing energy.
Catabolic
Breaking chemical bonds and releasing energy.
Reactants
Chemicals at the start of a chemical reaction.
Products
Results produced by a chemical reaction.
Activation Energy
Energy input required for a reaction to progress to products.
Exothermic/Exergonic
Energy is released. Reactants are at a higher energy level, products are at a lower energy level.
Endothermic/Endergonic
Energy is absorbed. Reactants are at a lower energy level, products are at a higher energy level.
Catalyst
A substance that speeds up the chemical reaction by lowering the activation energy (ex. Enzymes).
ATP
Energy currency of the cell. Adenosine Triphosphate. Consists of a nitrogenous base, ribose sugar, and 3 phosphate groups.
Hydrolysis
Addition of water to break bonds.
Phosphorylation
Addition of a phosphate group to a molecule to store energy.
Enzymes
Proteins that speed up reactions by lowering activation energy.
Substrate
The reactant that attaches to the enzyme and gets grabbed/moved/changed by the enzyme.
Active site
The place where the substrate attaches to the enzyme.
Lock and key model
Only one enzyme is used for one particular type of substrate.
Inhibitor
Something that slows down a reaction by blocking off the substrate from the reaction.
