NU 327 EXAM 1 - PATHOPHYSIOLOGY UPDATED ACTUAL
QUESTIONS AND CORRECT ANSWERS

Question:
1. Metabolism
Answer:
How do cells make energy?

Question:
2. aerobic and anaerobic metabolism
Answer:
two types of metabolism

Question:
3. aerobic metabolism
Answer:
happens INSIDE of the mitochondria; requires oxygen

Question:
4. anaerobic metabolism
Answer:
happens OUTSIDE of the mitochondria; also called glycolysis

Question:
5. 2 ATP
Answer:
result of anaerobic metabolism

Question:
6. 34 ATP
Answer:
result of aerobic metabolism

Question:
7. The sodium-potassium pump will not function at all
Answer:
What happens when there is energy failure?

Question:
8. Potassium
Answer:
intracellular ion

Question:
9. Sodium

,Answer:
extracellular ion

Question:
10. The sodium-potassium pump binds three sodium ions and a molecule of ATP.
Answer:
1st Step of the Sodium Potassium Pump

Question:
11. The spitting of ATP provides energy to change the shape of the channel. The sodium ions are driven
through the channel.
Answer:
2nd Step of the Sodium Potassium Pump

Question:
12. The sodium ions are released to the outside of the membrane, and the new shape of the channel allows
two potassium ions to bind.
Answer:
3rd Step of the Sodium Potassium Pump

Question:
13. Release of the phosphate allows the channel to revert to its original form, releasing the potassium ions
on the inside of the membrane.
Answer:
4th Step of the Sodium Potassium Pump

If recessive gene is "shown" then both parents _____________________.

Question:
26. carrier
Answer:
If a person has one dominant and one recessive allele from parents then daughter gene is said to be a
_____________.
