Second stage of glucose breakdown |
|
|
FAD (flavin adenine dinucleotide |
A high-energy electron-carrier to NADH. |
Krebs cycle, FAD picks up 2 energetic electrons along w/ 2 H+ |
|
|
Glycolysis |
Splits the six-carbon glucose molecule into two molecules of pyruvate. |
Greek: "glyco"-"sweet"; "lysis"-"to split apart" |
|
|
Kreb's cycle |
Set of mitochondrial matrix reactions |
Citric acid cycle |
|
|
Lactic acid fermentation |
Anaerobic reactions that convert the pyruvic acid produced by glycolysis into lactic acid, using hydrogen ions and electrons from NADH |
|
|
|

Cytosol, mitochondria, cellular respiration |
|
|
|
Conditions in which oxygen is absent are described as ____. In the absence of oxygen, some microorganisms break down glucose using ____, which generates only _____ molecules of ATP. |
Anaerobic, glycolysis, two |
|
|
|
This process is followed by ____, in which no more ATP is produced, but the electron-carrier molecule ____ is regenerated so it can be used in further glucose breakdown. |
Fermentation, NAD+ |
