Interconversion of glyceraldehyde-$3$-phosphate and dihydroxyacetone phosphate is catalysed by which enzyme?

In glycolysis,the two $ATP$ molecules are consumed during . . . . . . .

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.
Choose the correct option containing appropriate statements from the above.

Describe the process represented by the equation: $C_6H_{12}O_6 \to 2CH_3COCOOH + 2ATP + 2NADH + 2H^+$

The first phase in the breakdown of glucose in animal cells is

During cellular respiration,the number of $ATP$ molecules used during the conversion of glucose into glyceraldehyde-$3$-phosphate is:
