Metabolism
Metabolism
● The sum of all chemical reactions in a cell or organism
Energy
● Is defined as the capacity to do work
● There are two forms of energy: Kinetic energy and Potential Energy
Kinetic Energy
● Energy of motion
● Examples: waves in the ocean, falling rocks, molecules and ions moving in a solution
● Is present in movement is useful because it can perform work by making other objects
move
Potential Energy
● Stored within an object and is dependent on
the object's location or chemical structure
First Law of Thermodynamics
● Energy in the universe can be converted and
transformed from one form to another, but
energy cannot be created or destroyed - the
total energy remains constant
, Energy and Chemical Bonds
Bond Energy
● Bond energy is the measure of the strength or stability of a covalent
bond
● Measured in kJ per mole (kJ/mol)
● The amount of energy absorbed when a bond is broken
