AP Bio Chapter 9 Vocabulary (Cellular Respiration)
The vocabulary for chapter 9 and 10 of AP biology - cellular respiration and photosynthesis. (from Campbell text)
partial degradation of sugars that occurs without the use of oxygen (catabolic process)
a catabolic pathway where oxygen is consumed as a reactant along with the organic fuel
anaerobic and aerobic respiration
the loss of electrons from one substance
the addition of electrons to another substance
the electron donor
the electron acceptor
nicotinamide adenine dinucleotide, an electron carrier
Electron Transport Chain
oxidative phosphorylation (occurs in inner membrane of mitochondria)
producing ATP, powered by the redox reactions of the electron transport chain
making ATP by an enzyme transferring phosphate group from a substrate molecule to ADP.
Acetyl Coenzyme A, which is produced by pyruvate
a protein complex which helps phosphorylate ADP into ATP
the gradient across a membrane used to drive cellular work
the H+ gradient
the fermentation where pyruvate is converted to ethanol
Lactic Acid Fermentation
the fermentation where pyruvate is reduced directly to NADH
organisms which only carry out fermentation or anaerobic respiration and cannot survive in the presence of oxygen
organisms which produce enough ATP to use either fermentation or respiration
