Answer: STABILITY OF THE DNA MOLECULE.
MOLECULAR STRUCTURE OF DNA.
EASY SEPARATION OF DNA
HIGH BOILING POINT OF WATER
COHESIVE FORCE HOLDING WATER MOLECULE TOGETHER
Explanation: Although Hydrogen bonds are weak,they help in stabilising the DNA.
Hydrogen Bonds are weak bonds which connects the Nitrogen bases together in a DNA,which gives the structure of the DNA.
They also aids the Easy separation of a DNA molecule.
The Hydrogen bonds are the main factor that ensures that the boiling temperature of water is high.
Hydrogen bonds are cohesive in nature, they bind water molecules together through and cause it to resist heat and high temperature.

Answer:
ΔG'° for the coupled reaction = -16.7 kJ/mol
<em>Note: The question is missing some parts. The complete question is as follows:</em>
<em>The first reaction in glycolysis is the phosphorylation of glucose:
</em>
<em>
Pi+glucose⟶glucose−6−phosphate+H2O
</em>
<em>This is a thermodynamically unfavorable process, with ΔG∘′= +13.8kJ/mol. In a liver cell at 37 ∘C the concentrations of both phosphate and glucose are normally maintained at about 5 mM each.</em>
<em>This very low concentration of the desired product would be unfavorable for glycolysis. In fact the reaction is coupled to ATP hydrolysis to give the overall reaction: ATP + glucose → glucose-6-phosphate + ADP + H+</em>
<em>What is the ΔG'° for the coupled reaction?</em>
Explanation:
The coupling of ATP hydrolysis which is a thermodynamically favourable reaction to the phosphorylation of glucose makes it favourable. Since the two reactions constitute a sequential reaction, their standard free energy changes are additive.
For ATP hydrolysis: ATP + H₂O ---> ADP + Pi ; ΔG'° = -30.5KJ/mol
For phosphorylation of glucose: Pi + glucose⟶glucose−6−phosphate + H2O ; ΔG'° = +13.8 kJ/Mol
For the overall reaction: ATP + glucose → glucose-6-phosphate + ADP + H⁺ ; ΔG'° = 13.8 + (-30.5) kJ/mol = -16.7 kJ/mol
Therefore, ΔG'° for the coupled reaction = -16.7 kJ/mol
