Q. Which of the following conversions involve ATP synthesis during glycolysis?

Respiration in Plants

Solution:

In the energy conserving phase of glycolysis, the conversion of $B P G A$ to $P G A$ is catalysed by phosphoglycerate kinase. The phosphate on carbon 1 is transferred to a molecule of $A D P$, yielding $A T P$ and 3 -phosphoglycerate. This type of $A T P$ synthesis, traditionally referred to as substrate-level phosphorylation, involves the direct. transfer of a phosphate group from a substrate molecule to $A D P$, to form ATP .1,3 bisphosphoglycerate + ADP $\xrightarrow[Mg^{2+}]{\text{Phosphoglycerate kinase}} 3, 6$ - phosphoglycerate +ADP
