Term
Metabolism
Definition
Total chemical reactions in an organism
Term
Metabolic Pathway
Definition
Begin with a specific molecule and end with a product-is a collection of chemical reactions
Term
Catabolic Pathway
Definition
Release energy by breaking complex molecules into simple molecules
Term
Hydrolysis
Definition
Common in catabolic Pathway-breaking of a bond because water
Term
Anabolic Pathway
Definition
Consume energy to build complex molecule from simple molecule
Term

Definition
Common in anabolic pathway-Formation of bond by the loss of water
Term
Bioenergetics
Definition
Study of how organisms manage their energy resources
Term
Energy
Definition
Capacity to cause change
Term
Free Energy
Definition
Energy that can do work when the temperature and pressure are uniform in a cell

Definition
Any change in free energy
Term
Exergonic Reaction
Definition
Proceeds with a net release of free energy; Is changeG is negative and loses energy
Term
Endergonic Reaction
Definition
Absorbs free energy from surroundings;ChangeG is positive and gains energy
