3. NAD+ is an example of a good electron carrier
4. The net yield of ATP per glucose in glycolysis is 4 ATP
5. The citric acid cycle occurs in the inner mitochondrial membrane
6. Surface area to volume ratio decreases as an animal gets larger
7. Conformers are organisms whose internal (body) environment changes with change
in external environment

9. The ascending loop of Henle is permeable to water
10. All urea is excreted in human urine
11. Mosquitoes are examples of substrate-feeders
12. The digestive tract is an example of intracellular digestion
13. Animals "breathing" in water use bi-directional flow

16. Calcium is the metal ion that can be found in hemoglobin
17. The contraction phase of the cardiac cycle is called systole
18. Humans and other mammals have an open circulatory system
19. Fever is a localized inflammatory response
20. Immunization introduces antigens into the body
21. The anterior pituitary releases ADH
22. Astrocytes are glial cells that provide structural support
23. Graded potentials occur when there is a small change in membrane potential where
magnitude varies with the size of the stimulus
24. Depolarization occurs with K+ voltage-gated channels open
25. The afferent division of the PNS transmits motor information
26. Sympathetic nerves stimulate a "fight or flight" response
27. Memorization involves neurons making new connections
28. The somatic nervous system stimulates smooth muscle
29. There is no difference in action potentials coming from your eyes, nose or ears.

, 2. How many NET ATP have been produced by the end of the citric acid cycle? (1 point)
3. Describe what happens in the electron transport chain (what enters, what is the process
that takes place and what is produced?) (5 points)
4. Are more or less ATP produced in anaerobic respiration (compared to aerobic
respiration)? Why? (2 points)
5. Draw an example of countercurrent exchange and explain briefly. (4 points)
6. What is the thermal neutral zone? Draw a graph showing metabolic rate versus
environmental temperature to explain this concept. (4 points)

, 7. What is the purpose of osmoregulation? (1 point)
8. Explain how fish in seawater deal with osmotic stress. (3 points)
9. Name the 3 steps in obtaining energy that precede elimination of wastes. (1 point)
10. Write in order the path followed by a piece of food when it enters a cow's stomach from
the following list: omasum, reticulum, rumen, abomasum. At which point is water
reabsorbed? (2 points)
11. There are three types of cells in the stomach (parietal cells, chief cells and mucous cells).
Describe the function of each and why this is important (6 marks)
