The value of Δ G ° ' for the conversion of 3-phosphoglycerate to 2-phosphoglycerate (2PG) is + 4.40 kJ/mol . If the concentratio

Mrac [35]

Answer:The concentration of 2-phosphoglycerate is 0.415 mM

Explanation:

$3-phosphoglycerate\rightleftharpoons 2-phosphoglycerate$

Relation between standard Gibbs free energy and equilibrium constant follows:

$\Delta G^o=-RT\ln K$

where,

$\Delta G^o$ = Standard Gibbs free energy = +4.40 kJ/mol = 4400 J/mol (Conversion factor: 1kJ = 1000J)

R = Gas constant = $8.314J/K mol$

T = temperature = $25^0C=(25+273)K=298 K$

Putting values in above equation, we get:

$4400J/mol=-(8.314J/Kmol)\times 298K\times \ln K$

$\ln K=-1.776$

$K=0.169$

$K=\frac{ 2-phosphoglycerate}{3-phosphoglycerate}$

$0.169=\frac{ 2-phosphoglycerate}{2.45mM}$

$2-phosphoglycerate}=0.415mM$

Thus the concentration of 2-phosphoglycerate is 0.415 mM

fenix001 [56]

Answer: Part 1: The reaction is considered as replacement reaction and produce preciptate.

Part 2: Due to Mg is more active than Al.

Explanation:

Part 1: the reaction is replacement reaction due to the ions is replaced with each other as this equation shows:

MgCl2 + Na2CO3 → MgCO3 + 2NaCl

and MgCO3 is a white precipitate.

Part 2:

Al reacts with CuCl2 because Al is more active than Cu.

Al can not react with MgCl2 because Mg is more active than Al.

Glycolysis is the first step of cellular respiration, in which glucose is used to generate atp to power the cell. the major chem

Tanya [424]

The reaction of glycolysis is follows:

C6H12O6 + 2 NAD+ + 2 ADP + 2 P -----> 2 pyruvic acid + 2 ATP + 2 NADH + 2 H+

A glucose molecule produces 2 mole of pyruvic acid. For glycolysis, 2 molecule of NAD+ reduce to NADH by oxidising the glucose molecule to produce acid along with the production of 2 protons. This complete reaction, generates 2 mole of ATP.
