WGU C190- Module 5, 6, 7 Intro to Biology Exam Questions and
Answers with Verified Solutions | Latest 2026 Update
Q: Amino Acids
Answer:
building blocks of proteins
Q: carbohydrates
Answer:
the starches and sugars present in foods
Q: fats
Answer:
lipids that are solid at room temperature; composing of glycerol and saturated fatty
acids
Q: 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
Q: hydrophillic
Answer:
attracted to water (polar); refers to molecules that are water soluble
Q: hydrophobic
Answer:
Having an aversion to water; molecules do not interact with water and are
characterized by complete lack of electronegative atoms
Q: 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)
, Q: 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.
Q: monomer
Answer:
A small organic molecule that may bind chemically to other molecules to form a
polymer
Q: 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)
Q: Oils
Answer:
fats that are liquid at room temperature; a type of lipid composed of glycerol and
unsaturated fatty acids
Q: Organic molecules
Answer:
molecules that contain carbon that is covalently bonded with a hydrogen atom
Q: Phospholipids
Answer:
a lipid consisting of a glycerol bound to two fatty acids and a phosphate group.
Q: Polymer
Answer:
A long molecule consisting of many similar or identical monomers linked together.
