Cellular Structure and Transport
Chapter 4 - Intro and section 1
- Explain the significance of compartmentalization of
materials in a cell
- Why is a cell’s limited? Explain what happens to the
surface to volume ration as a cell grows as well as its
effect on the viability of the cell.
Chapter 4 - Intro and section 1
- Compare and contrast the pros and cons of light
and electron microscopy
- how can we chemically analyze the structures of a
cell
- Compare and contrast prokaryotic and eukaryotic
cells in terms of size, structure and complexity
Chapter 4 - Intro and section 1
- Compare and contrast prokaryotic and eukaryotic
cells in terms of size, structure and complexity
Chapter 4 - section 5
- Describe the structure of the cell wall for plants
and bacteria including:
structural composition
Functions
mechanisms by which molecules move through it
Chapter 5.1
- Discuss the location and role each of the following
play in the plasma membrane
- phospholipids
- Integral, peripheral, transmembrane proteins
- Cholesterol
- glycolipids/glycoproteins
- Be able to relate the chemical composition of each
of the above to their location in the membrane
Chapter 5.2
- Differentiate between passive and active transport
in terms of energy requirements and concentration
gradient
- What criteria determine whether a molecule can
pass through the phospholipid bilayer using simple
diffusion?
- How does facilitated diffusion differ? Provide
several examples.
Chapter 5.2
- differentiate between each of the following:
channel protein
carrier protein
voltage-gated channel
ligand gated channel
Chapter 5.2 and Chapter 25.3
- In what ways can water move across the membrane?
- What do the terms hypertonic, hypotonic and
isotonic mean and how do they relate to the
movement of water?
-How is the movement of water influenced by more
than solute concentration in plants?
-Turgor pressure? Water potential?
- How do transpiration and water potential work
together to make sure water moves up the xylem of a
plant?
Chapter 5.3
- How does active transport differ?
- under what circumstances would a cell need to use
active transport to move a substance?
- describe how the sodium potassium pump works
Chapter 5.4
- Bulk transport – how do cells use vesicles to move
large quantities in and out of the cell
phagocytosis
pinocytosis
receptor mediated endocytosis
