The partial oxidation of glucose into pyruvic acid through a series of intermediate steps is known as?

The enzyme that catalyses the conversion of glucose-$6$-phosphate into fructose-$6$-phosphate is

Which $3C$ sugars are interconvertible during phosphorylation?

Glycolysis:
$I$. Causes partial oxidation of glucose (one molecule) to form $2$ molecules of pyruvic acid and $2$ $ATP$ as net gain.
$II$. Takes place in all living cells.
$III$. Uses $2$ $ATP$ at two steps.
$IV$. Scheme was given by Gustav Embden,Otto Meyerhof,and $J$. Parnas.
