Key Terms – Chapter 6
1. Aerobic – involving or requiring the presence of oxygen
2. aerobic respiration – oxygen-requiring cellular respiration. Includes glycolysis, the citric
acid cycle, and electron transfer phosphorylation.
3. alcoholic fermentation – fermentation pathway that produces ATP, ethanol, and CO2.
4. anaerobic – occurring in the absence of oxygen
5. cellular respiration – any of several pathways that break down organic molecules
(typically glucose) to form ATP and include an electron transfer chain.
6. citric acid cycle – also called the Krebs cycle. Cyclic pathway that dismantles acetyl-
CoA to produce CO2, NADH, FADH2 and ATP.
7. Fermentation – any of several anerobic pathways that break down organic molecules
(typically glucose) to produce ATP without the use of an electron transfer chain.
8. Glycolysis – set of reactions that collectively convert one molecule of glucose to two
molecules of pyruvate, two ATP, and two NADH. First part of fermentation and aerobic
respiration.
9. lactate fermentation – fermentation pathway that produces ATP and lactate.
