Studying for the biochemistry test so I don't get kicked out of honors.

Organisms All living things
Nutrition the process that provides the substances used by an organism for tissue repair or growth
Digestion Processing food for use by the organism
Respiration the process that released energy for use by cells
Metabolism All chemical activities that an organism performs to sustain life
Homeostasis The maintenance of a stable internal environment in spite of changes in external environment
Cell theory Every organism is made up of one or more cells; The cell is the basic unit of structure and function in all living things
Indicator Shows the presence of a certain substance. i.e. Litmus paper or benedict solution
Enzymes large complex protein molecules that control the rate of chemical reactions
The building blocks of proteins are amino acids
Elements found in proteins carbon, hydrogen, oxygen, and nitrogen
Where do the chemical processes of the organism take place? inside the organism's cells
Livings things are composed of tiny units called atoms
The center core of an atom is called the nucleu
Electron's charge: (-1), located around the nucleus
Proton's charge: (+1), located at the nucleus
Neutron (0), located at the nucleus
Why are atoms electrically neutral? Atoms have the same number of neutrons and protons, that why they're so electrically neutral.
A substance made up of one kind of atom Element i.e. silver
Carbon C

Oxygen O
Nitrogen N
Sulfur S
Phosphorus P
Magnesium Mg
Iodine I
Iron Fe
Calcium Ca
Sodium Na
Chlorine CI
Potassium K
Zinc Zn
When two or more elements combine chemically Compound
Elements combine to form compounds chemical bonding
Smallest particle of an element or compound capable of independent motion Molecule
atom that has gained or lost an electron Ion
bond that is formed when atoms lose or gain electrons ionic bond
when atoms produces compounds sharing electrons Covalent bonds
represents the chemical makeup of a compound Chemical formula
A formula that shows the kinds, numbers, and arrangement of atoms structural formula
Substances that start reactions reactants
substances formed by reaction products
