G Consider a uniport system where a carrier protein transports an uncharged substance A across a cell membrane. Suppose that at a certain ratio of [ A ] inside to [ A ] outside , the Δ G for the transport of substance A from outside the cell to the inside, A outside → A inside , is − 14.1 kJ/mol at 25°C. What is the ratio of the concentration of substance A inside the cell to the concentration outside?

Answer :  The ratio of the concentration of substance A inside the cell to the concentration outside is, 296.2

Explanation :

The relation between the equilibrium constant and standard Gibbs free energy is:

where,

= standard Gibbs free energy  = -14.1 kJ/mol

R = gas constant = 8.314 J/K.mol

T = temperature =

Q  = reaction quotient

= concentration inside the cell

= concentration outside the cell

Now put all the given values in the above formula, we get:

Thus, the ratio of the concentration of substance A inside the cell to the concentration outside is, 296.2

i had this on my unit activity, i can you if you are a plato student. are you a plato student?

lol idk man i guess u gotta ask bill nye the science guy
