Chapter 3 Anatomy

Anatomy terms

Element Said to be “pure” in the sense that it cannot be broken down or decom-posed into two or more different substances
Compounds Two or more elements are joined to form chemical combinations
Octet rule Atoms with fewer than eight electrons in the outer energy level will attempt to lose, gain, or share electrons with other atoms to achieve stability.
Isotopes Contain the same number of protons but different numbers of neutrons.
Ionic Bonds Chemical bond formed by the transfer of electrons from one atom to another
Covalent Bonds Chemical bond formed by the sharing of one or more pairs of electrons between the outer energy levels of two atoms
Hydrogen bonds Are much weaker forces than ionic or covalent bonds because they require less energy to break. Can exist between biologically important molecules.
Decomposition reactions Result in the breakdown of a complex substance into two or more simpler substances.
Exchange reactions Permits two different reactants to exchange components and, as a result, form two new products
Reversible reactions Proceed in both directions.
Metabolism All the chemical reactions that occur in body cells.
Catabolism Chemical reactions that break down larger food molecules into smaller chemical units and, in so doing, often release energy
Anabolism Chemical reactions that build larger and more complex chemical molecules from smaller subunits. Require energy.
Salt Any compound that results from the chemical interaction of an acid and a base
