Molecular and Cellular Biology Exam
Questions With Correct Answers
Activation Energy - answer✔✔least amount of energy needed for a chemical reaction to take
place
Amino Acid - answer✔✔building block or monomer of proteins
Carbohydrates - answer✔✔sugars; provide short term energy example: potato, pasta, cracker
Catalyst - answer✔✔enzymes; speeds up chemical reactions and lower activation energy
Cohesion - answer✔✔water is attracted to each other; sticky and clumps together into drops
Enzymes - answer✔✔act as catalysts and help complex reactions occur by speeding up reactions
and lowering activation energy.
Lipid - answer✔✔fats; long term energy; insulates the body
Macromolecule/ Biomolecule - answer✔✔occurs naturally in organisms; ex: carbohydrates,
lipids, proteins and nucleic acids
Monomers - answer✔✔is a molecule that may bind chemically to other molecules to form a
polymer; ex: nucleotides are the monomers of nucleic acids
Nucleic Acids - answer✔✔DNA and RNA; stores genetic information; information to create
proteins
Nucleotide - answer✔✔building block/ monomer for DNA and RNA, 3 parts are phosphate,
sugar, nitrogen base
Polarity - answer✔✔state of having two opposites sides; water has a positive end and a negative
end
Protein - answer✔✔large biomolecule consisting of chains of amino acids; ex: enzymes and
hormones
Universal Solvent - answer✔✔capable of dissolving a variety of different substances; water
