TermDefinition
element Substance that can't be broken down into simpler chemical substance.
atom Smallest particle of an element.
nucleus Poitively charged center of and atom.
isotope atoms of the samwe element that have diffrent numbers of neutrons in the nucleuos.
compound substance of atoms of two or more diffrent elements that are chemically combined.
covalent bond chemical bond formed when two or more atoms share electrons.
molecule group of atoms held together
ion An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving the atom a net positive or negative electrical charge.
ionic bond An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions.
metobolism s the set of life-sustaining chemical transformations within the cells of living organisms.
mixture is a material system made up of two or more different substances which are mixed but are not combined chemically.
solution way of resolving difficulty: a method of successfully dealing with a problem or difficulty.
pH pH is a measure of the acidity or basicity of an aqueous solution.
acid Any of a class of substances whose aqueous solutions are characterized by a sour taste, the ability to turn blue litmus red, and the ability to react with bases and certain metals to form salts.
base that part of a bodily organ by which it is attached to another more central structure of the organism
diffusion is that it results in mixing or mass transport, without requiring bulk motion.
dynamic equilibrium A system in a steady state since forward reaction and backward reaction occur at the same rate.
hydrogen bond A hydrogen bond is the electromagnetic attractive interaction between polar molecules in which hydrogen
polar molecule A molecule with a net dipole as a result of the opposing charges from polar bonds arranged asymmetrically.
amino acid are biologically important organic compounds made from amine and carboxylic acid functional groups, along with a side-chain specific to each amino acid.
carbohydrate is an organic compound comprising only carbon, hydrogen, and oxygen, usually with a hydrogen:oxygen atom ratio of 2:1
enzyme are large biological molecules responsible for the thousands of chemical interconversions that sustain life.[1][2] They are highly selective catalysts, greatly accelerating both the rate and specificity of metabolic reactions, from the digestion of food.
isometer compounds with a simple formula
lipid Lipids are a group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins
nucleic acids are polymeric macromolecules, or large biological molecules, essential for all known forms of life.
nucleotide are organic molecules that form the basic building blocks of nucleic acids, such as DNA and RNA.
peptide bond is a covalent chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, causing the release of a molecule of water.
polymer large molecule composed of many repeated subunits, known as monomers
