Gen Bio Unit 4a: Transport and Homeostasis

Theme 4: Energy and Homeostasis

Unit 4a: Transport and Homeostasis (Question-based Objectives)

Keywords: phospholipid bilayer, active transport, passive transport, diffusion, facilitated diffusion, membrane proteins, protein channels, enzyme activity, cell-to-cell recognition, cell signaling, transport of materials, osmosis, selectively permeable membrane, exocytosis, endocytosis, vesicles, homeostasis, negative feedback, positive feedback

Objectives:

  1. How does a cell separate what is inside the cell from what is outside the cell?
  2. How do cells get things in and out, as needed by the cell?
  3. How do cells maintain conditions inside that allow life to exist?

Activities/Labs:

  1. Cell Membranes Worksheet
  2. Cell Transport Activity
  3. Homeostasis Activity

Extensions:

  1. Structures and functions of membrane proteins
  2. Structure and function of sodium-potassium pumps

Further Research: hypotonic, hypertonic, isotonic, membrane potential, proton pump, cotransport, pinocytosis, receptor-mediated endocytosis
