Question

Glycolysis is the metabolic pathway that converts glucose into pyruvate. The free energy released in this process is used to form the high-energy molecules ATP. Glycolysis is a determined sequence of ten enzyme-catalyzed reactions. However, one of the steps in glycolysis does not occur spontaneously under standard state conditions: Glucose + HPO42- ? glucose-6-phosphate + H2O ?G?r = 13.4 kJ*mole-1 Can the reaction take place in the cytoplasm of a cell? The cytoplasm is an aqueous medium, where the concentrations are: [glucose] = 4.5 × 10-2 M [HPO42-] = 2.7 × 10-3 M [glucose-6-Phosphate] = 1.6 × 10-4 M [H2O] taken as 1M to simplify the calculation (but for reality, it should be 55.56 M). The temperature is 310 K (around body temperature).

Step 1

The reaction is: \[ \text{Glucose} + \text{HPO}_4^{2-} \rightarrow \text{glucose-6-phosphate} + \text{H}_2\text{O} \] Given: - \(\Delta G^\circ = 13.4 \, \text{kJ/mol}\) - \([\text{glucose}] = 4.5 \times 10^{-2} \, \text{M}\) - \([\text{HPO}_4^{2-}] = Show more…

00:01 The question asks to find whether the given reaction will take place here, whether the given reaction will take place or not.

00:20 And what is the reaction here? the reaction is glucose plus hpo -4 -2 negative, which forms glucose 6 -phosphate plus h2.

00:37 And the value of its dalg -not for the reaction is given here, which is 13 .4 kilojou, tool, per more.

00:50 And we have to tell whether this reaction will take place inside a cytoplasm or not.

00:56 Inside cytoplasm.

01:01 And what is given here? the concentration is given here of glucose, which is 4 .5 multiplied by 10 power minus 2 molarity.

01:11 The concentration of h .p .o .4 negative is given here, which is 2 .7 multiplied by 10 power minus 3 molarity.

01:19 And the concentration of of glucose 6 phosphate is given here which is 1 .6 multiply by 10 power minus 4 molarity and we will take the concentration of h2os 1 molarity and what is the temperature here temperature is also given which is 310 kelvin so let's see the explanation for it so first of all if we see the reaction is given here in the question the concentrations of all the reactants and products are given here and the temperature is given here.

02:08 So first of all, i will write an equation here which is del g is equal to minus rt lnk.

02:18 This is our first equation.

02:22 And here the reaction will take place only when del g is less than zero.

02:31 The reaction will take place when del g is less than zero...
