Metabolism
Energy
The capacity to do work
E chemical
E light
E sound
E heat
E gradient
ATP
energy unit used in the body
allows muscles to contract and move
Metabolism
Sum of all chemical reaction occurring in the body
Kinetic energy
Energy when something is in motion or movement
Potential energy
Stored and or stationary energy
Types of energy
Thermal (heat)
Kinetic
Light

Sound
Metabolism 1
, Kinetic
Gradient
Potential
Like chemical gradients
energy is to move things
high concentration of sodium, particles move to areas with low
concentration
Chemical
Potential
The food we eat represents chemical energy
Bonds in the molecules represent the chemical potential energy
Particles slightly vibrate at all times (vibrate more in heat and less in cold)
Laws of Thermal Dynamics
1. Energy can be transformed from one form to another, but the total amount of
must remain the same.
You cannot create or destroy energy
2. When energy transfer takes place it will increase Entropy (order/ energy that
cannot be used for work) of the universe and reduce the amount of energy
that can be used to do work
Loose energy when it is transferred from one to another
Reactions
Chemical reactions
Can result in net release of energy or net input of energy
Exergonic: Release of energy when it occurs
Endergonic: Input of energy that occura
Gibbs free energy: Amount of free energy available in a system to do work
