WHERE DOES GLYCOLYSIS OCCUR?
cytoplasm
of
all living cells
WHAT ARE THE MAIN STAGES OF GLYCOLYSIS?
Phosphorylation
of
glucose
to
glucose phosphate
Splitting phosphorylated glucose
Oxidation
of
triose phosphate
Production
of
ATP
PROCESS OF GLYCOLYSIS?
Two phosphate molecules
(from
hydrolysis
of
two ATP molecules
)
added
to
glucose
to make it
more reactive
Provides
energy
to
activate glucose
Lowers activation energy
for
enzyme-controlled reactions
Phosphorylated glucose split
into
two triose phosphate molecules
Hydrogen removed
from each
triose phosphate molecule
(
oxidation
)
Transferred
to
hydrogen-carrier molecules
(
NAD
-> becomes
reduced NAD
)
Enzyme-controlled reactions
convert each
triose phosphate molecule
into a
pyruvate molecule
using
two ATP molecules regenerated
from
ADP
PRODUCTS OF GLYCOLYSIS?
2 pyruvate
2 ATP
2 reduced NAD
HOW MANY CARBONS DOES TRIOSE PHOSPHATE CONTAIN?
3
HOW MANY CARBONS DOES PYRUVATE CONTAIN?
3
