TESTED QUESTIONS WITH CORRECT
ANSWERS | BRAND NEW!
Steroids - ✔✔✔ Correct Answer > carbon skeleton consisting of four
fused rings - amphipathic, rigid, planar
(eg. Cholesterol)
Hydrophobic interactions - ✔✔✔ Correct Answer > water molecules
are able to form H bonds among themselves, but not with the
hydrocarbon chains
Van der waals interactions - ✔✔✔ Correct Answer > attractive forces
between hydrophobic molecules
(weakest of all interactions)
Proteins - ✔✔✔ Correct Answer > polymers of amino acids
Protein - catalysis - ✔✔✔ Correct Answer > enzymes
,Page 2 of 20
Protein - defense - ✔✔✔ Correct Answer > antibodies
(immunoglobulins)
Protein - structural support - ✔✔✔ Correct Answer > collagen and
elastin in animal connective tissue
Keratin in hair, horns, feathers
Protein - transport - ✔✔✔ Correct Answer > hemoglobin
Membrane transporters
Protein - storage - ✔✔✔ Correct Answer > ovalbumin, casein, gluten,
zeins
Protein - communication - ✔✔✔ Correct Answer > hormones (eg.
Insulin)
Cell surface receptors (proteins can be highly specific)
Protein - movement - ✔✔✔ Correct Answer > actin, myosin (contractile
proteins) in muscle
Tubulin, dynein (motor proteins in microtubules
Amino acid monomers - ✔✔✔ Correct Answer > all amino acids
possess both an amino group and a carboxyl group
, Page 3 of 20
All amino groups have at least one asymmetric carbon
Nonpolar amino acids - ✔✔✔ Correct Answer > hydrophobic
Usually found in the center of the protein
Also found in proteins which are associated with cell membranes
Polar uncharged amino acids - ✔✔✔ Correct Answer > hydrophilic and
can form H bonds
Electrically charged amino acids - ✔✔✔ Correct Answer > acidic:
negatively charged
Basic: positively charged
Charge changes when the ph changes
Peptide bonds - ✔✔✔ Correct Answer > amino acids joined together by
dehydration reactions to give a peptide bond
Polypeptides - ✔✔✔ Correct Answer > any string of amino acids up to
50
Proteins - polypeptides - ✔✔✔ Correct Answer > complete and folded
into an active conformation
Consists of at least 50 amino acids
