cellular respiration

fermentation

partial degradation of sugars that occurs without O2
aerobic respiration

consumes organic molecules and O2 and yields ATP
cellular respiration includes both aerobi and anarobic respiration but is often used to refer to aerobic respiration
oxidation

substances loses electrons or is oxidized
reduction

substances gains electrons or is reduced the amount of positive charge is reduced
ETC

NADH passes the electrons to the electron transport chain
glycolysis

breaks down glucose into 2 molecules pyruvate
citric acid cycle

completes the breakdown of glucose
oxidative phosphorylation

accounts for most of the atp synthesis
glycolosis occurs in the cytoplas 2 major phases
- energy investment phase
- energy payoff phase
acetyl coa

pyruvate converted to this links the cycle to glycolysis
krebs cycle
- takes place mitochondrial matric
- oxidizes organic fuel derived from pyruvate generate 1atp 3 nadh and 1 fadh2 per turn
cytochromes

electrons passed through a number of proteins
alcohol fermentation

pyruvate converted to ethanol in 2 steps with the first releaseing CO2
lacic acid fermentation

pyruvate redued to nadh forming lactate as an end product with no release of co2
