, Glycolysis
Phosphorylation
and splitting
of glucose
Happens in the
cell cytoplasm
Phosphorylation.
Glucose (6C) is phosphorylated by 2ATP to form Fructose
Bisphosphate (6C).
Lysis.
Fructose Bisphosphate (6C) splits into 2 molecules of
Triose Phosphate (3C).
Oxidation.
Hydrogen is removed from each molecule of Triose
Phosphate (3C), this hydrogen transferred to coenzyme
NAD to form 2 Reduced NAD (NADH).
Dephosphorylation.
Phosphates are transferred from TP (3C) to form 4ATP
through substrate-linked phosphorylation.
Pyruvate production.
2 Pyruvate (3C) molecules are produced form the 2
Triose Phosphate (3C) mollecues.
Respiration 2
, Link Reaction
Decarboxylation
and
dehydrogenation
of Pyruvate
(3C).
Happens in the
mitochondrial
matrix.
1) Pyruvate (3C) enters the mitochondrial matrix by active
transport, requiring a small amount of ATP.
2) Pyruvate (3C) is oxidised by enzymes to produce Acetate
releasing CO2, this process also reduces coenzyme NAD (NAD+) to
NADH.
3) Acetate (2C) combines with Coenzyme A to form Acetyl Coenzyme
A (Acetyl CoA).
