A outside
→ Ainside, is 10.9 kJ/mol at 25°C.
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 AG for the transport of substance A from outside the cell to the inside,
What is the ratio of the concentration of substance A inside the cell to the concentration outside?
[A]inside
[A] outside
-81.28
Incorrect Answer
Choose the true statement about the transport of A under the conditions described.
Decreasing the concentration of the uniport protein in the membrane will cause AG to become a smaller
positive number.
Because AG is positive, the ratio [A] inside/[A] outside must be less than one.
Increasing [A] outside will cause AG for movement of Aoutside to Ainside to become a larger positive number.
Movement of Ainside to Aoutside will be spontaneous.
