Chapter 3, Problem 16P

Interpretation Introduction

(a) Interpretation:

When the temperature is at 37°C, the free energy change in kJ/mol for the transport of glucose from a medium into the cell is to be identified.

Concept introduction:

As per the given data, concentration of glucose inside the cell is 0.1mM and the concentration of glucose in the solution is 0.01Mm therefore it is observed that the cell is more concentrated than the surrounding energy spent in transporting glucose against the concentration. The difference in the molar free energies of regions 1 and 2 that is inside and outside the cell determines the free energy change. The chemical potential for a solute depends on the concentration of that solute and hence the reason for different molar free energies.

Interpretation Introduction

(b) Interpretation:

The intracellular and extracellular concentrations for the transport of glucose from the medium into the cell to determine the free energy change is to be identified.

Concept introduction:

The intracellular and extracellular concentrations for the transport of glucose are 1mM and 10mM respectively.

Interpretation Introduction

(c) Interpretation:

The required number of moles of ATP need to be hydrolyzed for per mole of glucose transported to make each process favorable to be identified.

Concept introduction:

The processes aredescribed in parts of a and b to be coupled to ATP hydrolysis as per the given data.
