The uniqueness of water as a chemical substance is attriuted to its unique properties. These properties include being a universal solvent, having a high specific heat (temperature moderator), cohesive and adhesive nature etc.

This wonderful properties of water is due to its POLAR nature, which is when a substance has both positively and negatively charged parts to it. This is possible because the oxygen atoms (O) of water molecules attract electrons more than hydrogen atoms (H).

This POLARITY of water molecule is responsible for the HYDROGEN BONDING between water molecules and hence, contributes to the properties of water mentioned in the question (universal solvent, temperature moderator, and cohesive behavior)

Answer:

Change in free energy (ΔG) = 1.43 kcal/mol

Explanation:

Free energy is the energy released by a diffusing molecule moving up or down a concentration gradient, across a membrane.

The formula for free energy change import into a membrane is given by the formula :

$\triangle G = \triangle G^0 + R \times T \times In\frac{[X]_{inside}}{[X]_{outsdie}}$

where:

$\triangle G = change\ in\ free\ energy\\\triangle G^0 = initial\ charge\ on molecule = 0 (Glucose\ molecule\ is\ uncharged)\\R = gas\ constant\ = 2 (cal/mol.K)\\T =Absolute\ temperature= \ ^oK = ^oC + 273 = 37 + 273 = 310\ ^oK (Note: body\ temperature\ = 37^oC)\\In = Natural\ logarithm\\$

$[X]_{inside} = concentration\ of\ glucose\ inside\ the\ cell = 0.5mM\\ {[X]}_{outside} = concentration\ of\ glucose\ outside\ the\ cell = 5mM$

$\triangle G = 0 + (2) \times (310) \times In\frac{[0.5]}{[5]} \\\triangle G = 620 \times In (0.1)\\\triangle G = 620 \times (-2.3)\\\triangle G = -1426\ cal/mol\\\triangle G = 1.43\ kcal/mol$
