BIO 365S Study Guide - Midterm Guide: Membrane Transport, Passive Transport, Osmotic Concentration
Human Physiology - Exam1 Study Guide
Exam Style
multiple choice questions (scantron only) – hormone pathways**, pay
attention to the endocrine pathways because he could switch things around
(primary first instead of teriary).
multiple multiple choice questions (graded by each answer)
Short answer and calculations (similar style of questions practiced in
discussion and assignments) – epithelial transport, box problem*,
endocrine problem.
Membrane transport
1. Definition of physiology
2. Definition of Teleological and mechanical
3. Homeostasis: definition and examples. Canon’s postulate
4. Membrane transport: understand how each molecule moves in and out of the
cell, Fick’s law, active and passive transport.
5. Osmolarity and Tonicity: definition, cells behave in each solution, and
calculation
a. Dehydration: getting rid of more water than anything else, more
solute concentrated. Concentration will be greater than starting
concentration. Solute ICF stays the same because only water moves
and mostly lose stuff in ECF.
b. Hemorrhage: not losing more water, but just losing things you started
with. Concentration remains the same from the start chart. ICF solutes
also stays the same because mostly non-penetrating solutes.
c. For both situations, carry ICF solute.
6. Transmembrane proteins. Compare ion channels and carriers with pumps
and 2nd active transporters.
7. Epithelial transport: membrane proteins on the apical and basolateral
membranes for absorption or secretion function.

Solute icf stays the same because only water moves and mostly lose stuff in ecf: hemorrhage: not losing more water, but just losing things you started with. Concentration remains the same from the start chart. Icf solutes also stays the same because mostly non-penetrating solutes: for both situations, carry icf solute, transmembrane proteins. Compare ion channels and carriers with pumps and 2nd active transporters: epithelial transport: membrane proteins on the apical and basolateral. Put glucose carrier on lining/ecf side, facilitated diffusion uses concentration gradient to move into ecf.
