Molecular and Cellualr Biology Test Questions with Correct Answers Fully Solved Latest 2025
Activation Energy - Answers least amount of energy needed for a chemical reaction to take place
Amino Acid - Answers building block or monomer of proteins
Carbohydrates - Answers sugars; provide short term energy
Catalyst - Answers enzymes; speeds up chemical reactions and lower activation energy
Cohesion - Answers water is attracted to ech other; sticky abd ckumps together into drops
Enzymes - Answers act as catalysts and help complex reactions occur by speeding up reactions and
lowering activation energy.
Lipid - Answers fats; long term energy; insulates the body
Macromolecule/ Biomolecule - Answers occurs naturally in organisms; ex: carbohydrates, lipids, proteins
and nucleic acids
Monomers - Answers is a molecule that may bind chemically to other molecules to form a polymer; ex:
nucleotides are the monomers of nucleic acids
Nucleic Acids - Answers DNA and RNA; stores genetic information; information to create proteins
Nucleotide - Answers building block/ monomer for DNA and RNA
Polarity - Answers state of having two opposites sides; water has a positive end and a negative end
Protein - Answers large biomolecule consisting of chains of amino acids; ex: enzymes and hormones
Universal Solvent - Answers capable of dissolving a variety of different substances; water
Law - Answers are simple andobvious statements about a phenomenon that never requires a second
guess, or an experiment to verify
Theory - Answers is a scientific explanation of an observed phenomenon. Explain why things are the way
they are
Prokaryote - Answers Single cell organism that lacks a nucleus and membrane bound organelles
Eukaryote - Answers Organisms whose cells contain nucleus and membrane-bound organelles; single-
cell or multicellular
Passive Transport - Answers movement of molecules across the cell membrane without energy; high to
low concentration
Active Transport - Answers use of energy to move molecules through the cell membrane against the
concentration gradient ( from low to high)
