Radiation Protection (Exam 2) Ch - 6, 7
Questions with Correct Answers
_______ is a science that explores living things and life processes - Answer-Biology

_______ can perform functions of the body such as conduction of nerve impulses,
contraction of muscles, support of various organs, and transportation of body fluids such
as blood - Answer-cells

___________ are the basic units of all living matter and are essential for life; they move,
grow, react, protect themselves, repair damage, regulate life processes, and reproduce
- Answer-cells

The __________ is the fundamental component of structure, development, growth, and
life processes in the human body - Answer-cell

What are the requirements for efficient cell operation - Answer--must be provided food
as a source of raw material
-must be supplied oxygen
-must have enough water for transport of substances into and out of the cell

Proper cell function enables the body to maintain ___________, which is the ability to
function in a normal manner despite any changes the body may undergo because of
outside influences such as stress, exercise, injury, or disease - Answer-homeostasis
(equilibrium)

if exposure to outside influences such as ionizing radiation damages the components
involved in molecular synthesis beyond repair, then cells either: - Answer-behave
abnormally or die

cells are made of ____________, the chemical building material for all living things -
Answer-protoplasm

this substance carries on the:
complex process of metabolism
reception and processing of food and oxygen
elimination of waste products

Protoplasm consists of ____________ compounds (those that contain carbon,
hydrogen, and oxygen) and ____________ compounds (those that do not contain
carbon - Answer-organic; inorganic

The 2 most important inorganic substances are: - Answer-water and mineral salts
(electrolytes)

, Water aids in sustaining life and is the most abundant inorganic compound in the body;
it normally accounts for _____________% of protoplasm - Answer-80-85%

The 4 major classes of organic compounds: - Answer-proteins, carbohydrates, lipids
(fats), and nucleic acids--all contain carbon

____________ is the basic component of all organic matter - Answer-carbon (by
combining with hydrogen, nitrogen, and oxygen, carbon makes life possible)

Of all the organic compounds, ____________ contains the most carbon - Answer-
protein

___________ are the most elementary building blocks of cells, and they constitute
approximately 15% of cell content; essential for growth, the construction of new body
tissue (acellular tissue such as hair and nails), and the repair of injured or debilitated
tissue - Answer-Proteins

Proteins are formed when organic compounds called ___________ combine into long,
chainlike molecular complexes - Answer-amino acids

____________ proteins such as those found in muscle provide the body with its shape
and form and are a source of heat and energy - Answer-structural enzyme

_____________ proteins function as organic catalysts, that is, agents that affect rate or
speed of chemical reactions without being altered themselves - Answer-Enzymatic
proteins (enzymes)

____________ can mend damaged molecules and are therefore capable of helping the
cell to recover from a small amount of radiation induced damage - Answer-repair
enzymes

work effectively in both diagnostic and therapeutic energy range; however if radiation
damage is excessive because of the delivered equivalent dose, the damage will be too
severe for repair enzymes to have a positive effect

The concept wherein the intent is to deliver enough radiation to kill cancerous cells in a
tumor while delivering a lesser than cell-killing equivalent dose to any surrounding
noncancerous tissue structure is known as a _________________ - Answer-therapeutic
ratio

___________ are chemical secretions manufactured by various endocrine glands and
carried by the bloodstream to influence the activities of other parts of the body; regulate
body functions such as growth and development - Answer-hormones
