Glycolysis, Krebs Cycle &
Electron Transport Chain
GLYCOLYSIS
Glycolysis is the metabolic pathway that converts
glucose C₆H₁₂O₆, into pyruvic acid, CH₃COCOOH.
The free energy released in this process is used to
form the high-energy molecules adenosine
triphosphate and reduced nicotinamide adenine
dinucleotide. Glycolysis is a sequence of ten
reactions catalyzed by enzymes.
GLYCOLYSIS
Glycolysis is a series of reactions that help extract energy from glucose.
Important in the cell because glucose is the main source of fuel for tissues in
the body.
Important because the metabolism of glucose produces useful intermediates
for other metabolic pathways, such as the synthesis of amino acids or fatty
acids.
KREBS CYCLE
Krebs cycle adds electrons and protons to a
number of electron carriers, which are then used by
the electron transport chain to produce ATP. ... This
molecule is acidic, which is why the Krebs cycle is also
called the tricarboxylic acid cycle
KREBS CYCLE
The citric acid cycle, also known as the Krebs cycle or the tricarboxylic acid
cycle, is at the center of cellular metabolism, playing a starring role in both
the process of energy production and biosynthesis. It finishes the sugarbreaking job started in glycolysis and fuels the production of ATP in the
process.
ELECTRON TRANSPORT CHAIN
The electron transport chain
 is a series of proteins and organic molecules found in the inner
membrane of the mitochondria.
creating an electrochemical gradient that leads to the creation of ATP
in a complete system named oxidative phosphorylation. It occurs in
mitochondria in both cellular respiration and photosynthesis.
