BIO 202: STUDY GUIDE/PRACTICE EXAM: MODULE 1
MEMBRANES AND MEMBRANE TRANSPORT
1. What are the basic structural arrangements and functions of phospholipids,
proteins and carbohydrates in a cell membrane?
2. What kinds of substances can or cannot pass through the cell membrane?
3. Describe each of the following. Be sure to note which processes require ATP and
work against the concentration gradient. Also name the kinds of substances
transported each way.
Diffusion
Osmosis
Facilitated
transport
Active transport
4. Define hypertonic, hypotonic, and isotonic
5. What kinds of solutions would cause a cell with 0.9% salt solution inside to lyse or
creanate:
5. What happens to the cell membrane during Pinocytosis, Phagocytosis, Exocytosis?
How do the processes differ?
TISSUES
1 What are the functions of epithelial tissues?
2. What are the major structural characteristics of epithelial tissue?
3. What holds epithelial cells together? What connects epithelial cells to the rest of
the body?
