BIO 101 Test 3 Liberty University
1. a Glycolysis (b) Krebs Cycle (c) Electron Transport Chain.: the three stages
of aerobic pathway of respiration
2. Respiration is the process by which the cell uses energy. Electrons from
energy-rich initial reactant end up combining with oxygen to form water
Fermentation is a short metabolic pathway in which electrons transferred
to NADH carrier molecules are finally accepted, not by oxygen but by some
organic molecule.: Know the difference between respiration and fermentation
3. Is the energy released by breaking bonds: the importance of the ATP molecule
4. Cytoplasm: o Know where glycolysis takes place
5. Energy requiring- ATP activates glucose Energy releasing steps- Products
are split into three carbon molecules and stored as ATP & NADH: Know the two
stages in glycolysis cycle
6. 2: Know how many ATP molecules are used in the first stage of glycolysis
7. 4: Know how many ATP molecules are produced in the 2nd stage
8. four ATP, two NADH, two ADP, and two pyruvate molecules: Know what
molecule is the end product of glycolysis (and how many of them are produced per
glucose molecule (look at the Carbon number)
9. 2 pyruvic acid, 2 NADH: Know what energy (electron) carrying molecule is
formed during glycolysis
10. NADH: What molecule is recycled in Krebs cycle?
11. Carbon Dioxide: Know what gas molecule is produced during the Krebs cycle
12. NADH, ATP, and FADH2,: Know what electron (energy) carrying molecules are
produced during the Krebs cycle
13. 2 ATP: Know how many ATP molecules are produced during the Krebs cycle
14. Inner membrane of mitochondria: Know where ELECTRON TRANSPORT
takes place
15. NADH & FADH2: Know what molecules from the Krebs cycle deliver energy
carrying electrons to the electron transport system
16. Oxygen: Know what molecule scoops up electrons that have been depleted of
their excess energy at the end of the electron transport system
17. alcoholic and lactate: the two types of fermentation
18. lactate produces 2 ATP & 2 NADH
Alcoholic produces Ethanol & Carbon Dioxide: Know what each produces
19. : Know what organisms use each of these and what human uses each has
20. Bacteria: Know what organisms use this in anaerobic electron transport
21. No oxygen: Know how it is different from fermentation and from aerobic electron
transport
