Illusion [34]

The level of the structure is the proteins in the secondary.

<h3>What is the structure of secondary?</h3>
  • A polypeptide chain's adjacent amino acid residues are arranged in regular patterns in space, known as secondary structure. It is kept in place by hydrogen bonds between the amide hydrogens and the peptide backbone's carbonyl oxygens. Helixes and structures are the two main secondary structures.
  • Local regions of proteins can be organized into one of three three-dimensional configurations: alpha helices (-helix), beta sheets (-strand), or omega loops. The alpha helix is the most prevalent secondary protein shape because it is stable and low-energy.
  • The interaction of amino acids with every backbone NH hydrogen bound with the backbone C=O group of the corresponding amino acid residue in the polypeptide chain results in the- helix formation. The- helix motif is particularly prevalent in transmembrane regions of proteins that traverse the lipid bilayer.

You are observing proteins in a lab for an experiment. During transport, they have started to unwind and lose their shape.

This very low concentration of the desired product would be unfavorable for glycolysis. In fact the reaction is coupled to ATP h
abruzzese [7]

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
