What
happens
in
A?
• Glycolysis and fermentation
• Anaerobic processes
• Formation of 2 ATP by substrate-level
phosphorylation
• Formation of NADH
A
B
C
D (the line)
What happens in B?
• Hydrogen ions (protons) are pumped into
this area by the electron transport chain.
• pH of this area decreases.

D (the line)
What happens in C?
• Oxidation of pyruvate & Krebs/Citric Acid Cycle
• NADH and FADH2 are produced
• ATP produced by substrate-level
phosphorylation (2 per glucose)
• CO2 produced (4 per glucose)
A
B
C
D (the line)
What happens in D?
• Electron Transport Chain (oxidation-reduction reactions)
• Water is produced.
• Hydrogen ions are pumped out of the matrix to the
intermembrane space
• An electrochemical gradient is produced across D.
• NADH and FADH2 are oxidized.

All of these components make up ATP except…
Phosphate group
Adenine
Thymine
Ribose
ATP stands for Adenosine
Triphosphate and is made up of
a phosphate group consisting of
3 phosphates, adenine, and
ribose. Thymine has nothing to
do with the structure of ATP but
is sometimes confused with the
T in ATP. When a phosphate is
broken off and released, energy
is released causing various
interactions in a cell.
Redox Reactions
Define redox.
Oxidation
The loss of electrons
Reduction
The gain of electrons
