EXSS 376 EXAM 1 UPDATED ACTUAL QUESTIONS AND
CORRECT ANSWERS

Question:
1. Most rapid energetic system, very limited but can produce a dick-load of fast energy. used with sprints,
jumps, throws, etc.
Answer:
ATP-CP system; uses creatine phosphorylate

Question:
2. 2nd most rapid energetic system; uses glycogen/glucose as fuel. limited in store, but not as limited as CP
system, system can last for a couple of minutes. produces fatiguing by-products
Answer:
Lactic Acid system

Question:
3. slowest energy system, but used for long duration exercises. uses glucose, fats, and very little protein.
doesn't produce fatiguing by-products.
Answer:
oxygen system

Question:
4. Energy to perform exercise comes from a ____ b/w aerobic and anaerobic pathways.
Answer:
interaction

Question:
5. Short-term, high intensity exercises use _____ energy systems.
Answer:
anaerobic

Question:
6. Long term, low to moderate intensity exercise uses ____ energy systems.
Answer:
aerobic. but some can come from anaerobic when aerobic capacity can't be sufficed.

Question:
7. T/F: ATP can be utilized much faster than it can be produced aerobically during high intensity exercise.
Answer:
True. This is why we need the ATP-CP system in order to regain some ATP very quickly.

Question:
8. This molecule is similar to ATP in that it contains high energy phosphate bonds; a small amount of it is
stored in the muscle

,Answer:
CP

Question:
9. This molecule provides energy for about 10 seconds of muscle activity, but can be quickly restored.
Answer:
CP

Question:
10. Who has greater ATP stores, males of females?
Answer:
Males have 3x more ATP stores than females.

Question:
11. Enzyme that catalyzes the ATP/PC system:
Answer:
creatine kinase

Question:
12. breakdown of glucose
Answer:
glycolysis

Question:
13. Formation of new glucose from non-glucose precursors (name the process and name non-g precursors)
Answer:
gluconeogenesis; fats, proteins, lactic acid

Question:
14. glycogen:
Answer:
stored form of glucose

Question:
15. storage form of glucose
Answer:
glycogen

Question:
16. formation of glycogen
Answer:
glycogenesis (stimulated by insulin)

Question:
17. breakdown of glycogen into glucose

, Answer:
glycogenolysis

Question:
18. name the four possible outcomes of glucose:
Answer:
storage as liver glycogen storage as muscle glycogen stored as fat utilized directly

Question:
19. one mole of glucose gives you ___ ATP
Answer:
32

Question:
20. what are the 2 by-products of aerobic metabolism, and what are their fates?
Answer:
CO2 --> diffuses into blood, exhaled at lungs
H2O --> used for many things

Question:
21. the three components of aerobic respiration
Answer:
1. aerobic glycolysis
2. krebs cycle
3. electron transport chain

Question:
22. series of reactions that degrades glucose into pyruvate
Answer:
glycolysis

Question:
23. if o2 is present, pyruvate is converted to..
Answer:
acetyl CoA

Question:
24. if o2 is absent, pyruvate is converted to..
Answer:
lactate

Question:
25. what is the role of oxygen after glycolysis?
Answer:
to accept a hydrogen from NADH. this allows us to continue further into aerobic respiration.
