Thermal energy is the kinetic energy associated with random movement of atoms or molecules
- The study of energy transformations in a collection of matter
- The energy of the universe is constant
- Energy can be transferred and transformed, but it cannot be created or destroyed
- every energy transfer or transformation increases the entropy of the universe
- Entropy is a measure of molecular disorder, or randomness
-
is the portion of a system's energy that can do work when temperature and pressure are uniform throughout the system, as in a living cell

is composed of ribose (a sugar), adenine (a nitrogenous base), and three phosphate groups
transfer of a phosphate group from ATP to another molecule, is typically used to power endergonic reactions
-
-
-
- cells manage energy resources to do work through energy coupling, the use of an exergonic process to drive an endergonic one
- Most energy coupling in cells is mediated by ATP
-
-
the initial energy needed to break the bonds of the reactants is called the activation energy. Heat in the form of thermal energy absorbed from the surroundings often supplies activation energy

an enzyme that binds to its substrate, while bound the catalytic activity of the enzyme converts substrate to product
the region on the enzyme, often a pocket or groove, that binds to the substrate
the complementary fit between the shape of the active site and the shape of the substrate is responsible for enzyme specificity
results from interactions between chemical groups on the substate and the active site. It brings the chemical groups of the active site into positions that enhance catalysis of the reaction
