Vedclass · Answer

(A) During glycolysis,$PGAL$ (glyceraldehyde-$3$-phosphate) is oxidized to $BPGA$ ($1,3$-bisphosphoglyceric acid).In this step,two redox-equivalents are removed from $PGAL$ in the form of hydrogen atoms and transferred to a molecule of $NAD^{+}$ to form $NADH + H^{+}$.$PGAL$ also reacts with inorganic phosphate $(Pi)$ to form $BPGA$.Subsequently,$BPGA$ is converted into $3$-phosphoglyceric acid $(PGA)$ by the enzyme phosphoglycerate kinase,a process that yields $ATP$ from $ADP$.

How is $PGA$ formed from $PGAL$?
