CHAPTER 2 TEST: CELL AND CELL MEMBRANE
Cell Organelles
vocabulary: eukaryotic, prokaryotic, nucleus (chromosome, nucleolus, nuclear pore, nuclear
envelope), endoplasmic reticulum (smooth, rough), endomembrane system, vesicles, Golgi
apparatus, lysosomes, peroxisomes, vacuole, chloroplast, mitochondria, cell wall, cytoskeleton,
cilia, flagella
Cell membranes
vocabulary: phospholipid bilayer, glycoproteins, integral proteins, peripheral proteins, semipermeable, channel protein, carrier protein,
Cell membrane transport
vocabulary: solution, hypotonic, hypertonic, isotonic,passive transport, concentration gradient,
diffusion, osmosis, facilitated diffusion,
vocabulary: active transport, membrane-assisted transport, endocytosis, exocytosis,
phagocytosis, pinocytosis, receptor-mediated endocytosis
1. Draw and explain a diagram of membrane-assisted transport, from the synthesis of a
peptide-based hormone (like insulin) on the rough endoplasmic reticulum to its release at
the cell surface.
- your diagram will need to include
- transcription/translation
- protein folding
- endomembrane transport
- use of and source of energy in the transport
2. Some molecules require active transport while others can use some form of diffusion.
Create a chart to show which molecules use which form of transport. What proteins are
involved?
3. Reverse question (1) to show the endocytosis and digestion of a virus by a cell
- your diagram will need to include
- attachment of virus to cell glycoproteins
- endomembrane transport including lysosomes
- use of and source of energy in the transport
- use of macromolecules following digestion of virus
