occurs when new bonds form or old bonds break between atoms.
CHEMICAL REACTION
refers to all the chemical reactions occurring in the body.
METABOLISM
the capacity to do work
ENERGY
energy stored by matter due to its position
POTENTIAL ENERGY
energy associated with matter in motion
KINETIC ENERGY
a form of potential energy that is stored in the bonds of compounds and molecules.
CHEMICAL ENERGY
Although energy can be neither created nor destroyed, it may be converted from one form to another.
LAW OF CONSERVATIVE ENERGY
release more energy than they absorb.
EXERGONIC REACTIONS
absorb more energy than they release
ENGERGONIC REACTIONS
The collision energy needed to break the chemical bonds of the reactants is called
ACTIVATION ENERGY
chemical compounds that speed up chemical reactions by lowering the activation energy needed for a reaction
CATALYST
When two or more atoms, ions, or molecules combine to form new and larger molecules, the processes are called
SYNTHESIS REACTIONS
split up large molecules into smaller atoms, ions, or molecules.
DECOMPOSITION REACTIONS
All of the synthesis reactions that occur in your body are collectively referred to
ANABOLISM
The decomposition reactions that occur in your body are collectively referred
