ANSWERS 2026 - 2027
How do the plasma membrane and the lysosomal membrane in an
animal cell differ from each other?
The plasma membrane and the lysosomal membrane have different
proteins.
Which of the following is NOT a way in which cell types differ from
each other?
Not all cells are enclosed by a membrane.
When viruses infect cells, they bind to receptor proteins in the cell's
plasma membrane. These receptor proteins are ________ because
the part embedded in the phospholipid bilayer is _______ and the
part outside the cell that contacts the virus is _______.
The blanks above should be filled in with which of the following
words (in order)?
amphipathic, hydrophobic, hydrophilic
Hemoglobin is the protein responsible for transporting oxygen in
the bloodstream of many animals. It is composed of four subunits,
two alpha chains and two beta chains, with each chain arranged into
a set of alpha-helix structural segments associated with an iron-
containing heme group. The alpha and beta chains are coded for by
different genes. Which of the following terms would apply to
hemoglobin?
i. Secondary structure

Which of the following results would support the hypothesis that
Australian Redback Spider females cannibalize their mates because
they mistake them for prey?
Females sometimes attack males as soon as the male enters the web,
similar to the way they attack their prey.
Which of these is NOT true of active learning approaches, in which
students actively engage with the material they are studying?
Active learning is useful for students from kindergarten through high
school, but not at the college level.
Transduction
conversion of one form of energy into another. In sensation, the
transforming of stimulus energies, such as sights, sounds, and smells,
into neural impulses our brains can interpret.

QUESTIONS AND
ANSWERS 2026 - 2027
How many different amino acids are there?
20
How do the properties of the side chain affect these amino acids'
interactions with other amino acids? With water? (Polar)
They are hydrophilic (water-loving) and form hydrogen bonds with
water molecules, making them soluble. They are usually found on the
outer surface of proteins.
How do the properties of the side chain affect these amino acids'
interactions with other amino acids? With water? (Nonpolar)
They are hydrophobic (water-fearing) and do not form hydrogen bonds
with water. They disrupt water structure, so they are driven away from
water into the protein interior. [1, 2, 3]
How do the properties of the side chain affect these amino acids'
interactions with other amino acids? With water? (charged)
They are strongly hydrophilic and form ionic interactions and hydration
shells with water molecules, keeping them highly soluble on the protein
surface.

QUESTIONS AND
ANSWERS 2026 - 2027
The unique, linear sequence of amino acids in a single polypeptide
chain.
secondary structure
The localized folding or coiling of the polypeptide backbone into
regular structural motifs. The two most common types are the alpha-
helix and beta-pleated sheet
tertiary structure
The overall, comprehensive three-dimensional shape of a single, entire
polypeptide chain folded into a compact globular or fibrous
conformation.
quaternary structure
The overall, comprehensive three-dimensional shape of a single, entire
polypeptide chain folded into a compact globular or fibrous
conformation.

A digestive enzyme that cleaves proteins in our food.
How many protein strands are present in pepsin?
