WGU C190- MODULE 5, 6, 7 INTRO
TO BIOLOGY EXAM WITH
CORRECT ANSWERS (GRADED A)
Amino Acids - ....ANSWER ...-building blocks of proteins
carbohydrates - ....ANSWER ...-the starches and sugars present in foods
fats - ....ANSWER ...-lipids that are solid at room temperature; composing
of glycerol and saturated fatty acids
glucose - ....ANSWER ...-a simple sugar that is an important energy source
in living organisms and is a component of many carbohydrates; primary product
(output) of photosynthesis and primary reactant (input) of cellular respiration
hydrophillic - ....ANSWER ...-attracted to water (polar); refers to molecules
that are water soluble
hydrophobic - ....ANSWER ...-Having an aversion to water; molecules do
not interact with water and are characterized by complete lack of electronegative
atoms
....COPYRIGHT ©️ 2025 ALL RIGHTS RESERVED...TRUSTED & VERIFIED 1
, inorganic molecules - ....ANSWER ...-simple molecules not found in living
things; molecules that do not contain both carbon and hydrogen (however could
contain one) (e.g.; salts, strong acids and bases, metal compounds)
Lipids - ....ANSWER ...-organic macromolecules that are largely nonpolar
(electrons are evenly distributed among atoms in a molecule) and as a result are
hydrophobic.
Perform many functions in the cell including storage of energy for long-term use in
the form of fats, insulation from the environment, and building blocks for
hormones. Include fats, oils, waxes, phospholipids, and steroids.
monomer - ....ANSWER ...-A small organic molecule that may bind
chemically to other molecules to form a polymer
Monosaccharides - ....ANSWER ...-a simple sugar (carbohydrate) containing
carbon, hydrogen and oxygen atoms in a 1:2:1 ratio respectively.
(Glucose, fructose and ribose are examples)
Oils - ....ANSWER ...-fats that are liquid at room temperature; a type of lipid
composed of glycerol and unsaturated fatty acids
Organic molecules - ....ANSWER ...-molecules that contain carbon that is
covalently bonded with a hydrogen atom
