Molecular Biology of the Cell
Comprehensive Test Bank QUESTIONS &
ANSWERS | A+ GRADED 100% VERIFIED
• What is the primary focus of cell biology? -✓✓The study of cells,
based on the premise that studying parts can explain the whole.
• Who first termed the 'cells' in cork? -✓✓Robert Hooke
• What did Anton van Leeuwenhoek observe in pond water? -
✓✓Teeming microscopic 'animalcules' and bacteria.
• What are the three main components of cell theory? -✓✓1. All
organisms are composed of one or more cells. 2. The cell is the
structural unit of life. 3. Cells arise only by division from pre-existing
cells.
• What additional concept was added to cell theory? -✓✓Cells contain
genetic information (DNA) passed to the next cell generation.
• What are HeLa cells? -✓✓Cultured tumor cells isolated from a cancer
patient, Henrietta Lacks.
• What do genes encode? -✓✓Information for building an organism,
including instructions for constructing cellular structures and running
cellular activities.
, • How do cells reproduce? -✓✓By division, distributing the contents of a
'mother' cell into two 'daughter' cells.
• What is the primary source of energy for animal cells? -✓✓Glucose
derived from photosynthesis.
• What role do enzymes play in cells? -✓✓They increase the rate of
chemical reactions, representing the cell's metabolism.
• What activities can cells perform? -✓✓Transport materials,
assemble/disassemble structures, and move from one site to another.
• How do cells respond to stimuli? -✓✓By altering metabolism, moving,
or committing suicide.
• What is self-regulation in cells? -✓✓Cells maintain a stable state
through feedback circuits and constant regulation.
• What is the last universal common ancestor (LUCA)? -✓✓The ancient
cell from which all living organisms evolved, existing over three billion
years ago.
• What are the two fundamentally different classes of cells? -
✓✓Prokaryotic (bacteria) and Eukaryotic (plants, animals, protists,
fungi).
• What distinguishes prokaryotic cells from eukaryotic cells? -
✓✓Prokaryotic cells lack membrane-bound organelles and have genetic
material in the cytosol, while eukaryotic cells have a nucleus.
