(N/A) Glycolysis is the partial oxidation of glucose into two molecules of pyruvic acid. The process occurs in the cytoplasm of the cell and involves the following steps:
$1$. Glucose $(6C)$ is phosphorylated to Glucose-$6$-phosphate using $ATP$.
$2$. Glucose-$6$-phosphate is isomerized to Fructose-$6$-phosphate.
$3$. Fructose-$6$-phosphate is phosphorylated to Fructose-$1,6$-bisphosphate using another $ATP$.
$4$. Fructose-$1,6$-bisphosphate splits into two $3C$ molecules: Glyceraldehyde-$3$-phosphate $(GAP)$ and Dihydroxyacetone phosphate $(DHAP)$,which are interconvertible.
$5$. $GAP$ is oxidized and phosphorylated to form $1,3$-bisphosphoglyceric acid,producing $NADH + H^+$.
$6$. $1,3$-bisphosphoglyceric acid is converted to $3$-phosphoglyceric acid,generating $ATP$.
$7$. $3$-phosphoglyceric acid is converted to $2$-phosphoglycerate.
$8$. $2$-phosphoglycerate is dehydrated to form phosphoenolpyruvate $(PEP)$,releasing $H_2O$.
$9$. $PEP$ is converted to Pyruvic acid $(3C)$,generating another $ATP$.
