CERTIFICATION EVALUATION EXAMS 2026
COMPLETE QUESTIONS AND ANSWERS
GUARANTEED TO PASS
◉ Number of different proteins in human body.
Answer: Over 20,000
◉ Protein transport function.
Answer: Move molecules around cell and organism. Ex: hemoglobin
carries O from lungs to tissues
◉ Protein hormone function.
Answer: communicate messages between cells. Ex: relaxin relaxes
pelvic ligaments during birth
◉ Protein catalysis function.
Answer: Enzymes. Speed up or catalyze reactions. Ex: protease,
breaks down other proteins
◉ Protein structure function.
Answer: Give strength to cells, organelles, and tissues. Ex: collagen
,◉ Protein protection function.
Answer: Help fend off bacteria and viruses, antibodies are proteins
◉ Amino acids.
Answer: monomers of protein
◉ Functional groups of in all amino acids.
Answer: carboxylic acid and amine group
◉ C alpha.
Answer: Central carbon connecting amine and carboxylic acid
functional groups.
◉ Location of C alpha.
Answer: adjacent to carboxylic acid group
◉ Effect of pH 7.4 on amino acid fuctional groups.
Answer: Carboxylic acid group loses hydrogen; Amino groups gain
an extra proton
◉ Non-polar aliphatic.
, Answer: Glycine
Alanine
Valine
Proline
Leucine
Isoleucine
Methionine
◉ Non-polar aromatic amino acids.
Answer: Phenylalanine
Tryptophan
Tyrosine
◉ Characteristics of aliphatic amino acids.
Answer: small, can interact with other groups; often found on
interior of protein, away from water
◉ Unique properties of proline.
Answer: non-flexible structure; side chain bonds to N
◉ Characteristics of non-polar aromatic groups.
