Anatomy and Physiology: The Unity of Form and Function
Chapter 2
Biochemistry - (correct Answer) - the study of the molecules that compose living organisms
Element - (correct Answer) - the simplest form of matter to have unique chemical properties
Trace Elements - (correct Answer) - An element indispensable for life but required in extremely minute
amounts.
Radioisotopes - (correct Answer) - unstable isotopes
Radioactivity - (correct Answer) - the process of decay of Radioisotopes
Ionizing Radiation - (correct Answer) - Enough energy to dislodge electrons from atoms, forming ions;
capable of causing cancer (gamma, X-rays, UV)
Physical Half-Life - (correct Answer) - the time required for 50% of its atoms to decay to a more stable
state
Ions - (correct Answer) - charged particles with unequal number of protons and electrons
Anion - (correct Answer) - A negatively charged ion
Cation - (correct Answer) - A positively charged ion
Electrolytes - (correct Answer) - substances that ionize in water and form solutions capable of conducting
electricity
Free Radicals - (correct Answer) - chemical particles with an odd number of electrons
Molecules - (correct Answer) - chemical particles composed of two or more atoms united by a chemical
bond
Compounds - (correct Answer) - molecules composed of two or more elements
Isomers - (correct Answer) - molecules with identical molecular formulaes but different arrangements of
their atoms
Molecular Weight - (correct Answer) - the sum of the atomic weights of its atoms
Antioxidant - (correct Answer) - a chemical that neutralizes free radicals
Chemical Bonds - (correct Answer) - A union between the electron structures of two or more atoms
Ionic bond - (correct Answer) - the attraction of a cation to an anion
Covalent bonds - (correct Answer) - Bonds created by sharing electrons with other atoms.
