What is the significance of the gapdh reaction in e. coli to glycolysis?

Ans.

The GAPDH (glyceraldehyde-3-phosphate dehydrogenase) is a catalytic protein that converts glyceraldehyde-3-phosphate into 1,3-BPG (1,3-bisphosphoglycerate) during glycolysis. The 1,3-BPG contains a high-energy phosphate group, which is transferred to the ADP to form ATP, the energy currency of the cell, in the next step of glycolysis.

Thus, in E.coli., 'GAPDH helps in the 1,3-BPG that helps in ATP formation and provides energy to the cell.'

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
