In the lab, you use a special balloon that is permeable to water but not sucrose to make an "artificial cell." The balloon is fi
WARRIOR [948]

Answer:

The correct answer is B. water will leave the balloon.

Explanation:

As the sucrose concentration is higher in the solution, the water in the balloon, where the sucrose is less concentrated, will tend to leave and try to dilute the outer solution until both sucrose concentrations are equal. But as the water leaves the balloon, the concentration inside will increase, so it will flow outside until both concentrations are equal and not until the outer concentration is similar to the initial concentration in the balloon.

The plasma membrane represents an energetic barrier to the free diffusion of ions from the extracellular space into the cytoplas
Marysya12 [62]

Answer:

Why are molecules such as valinomycin effective at transporting ions across the membrane?

Valinomycin is effective as transporting ions across the membrane because it is no charged, so it can carry ions.

Why would a drop in temperature to or below the transition temperature limit valinomycin mediated K+ transport across the plasma membrane?

Valinomycin is limited by temperature because its activity is highly sensitive and it depends on a stable and an average temperature.

Explanation:

Valinomycin is effective at transporting ion across the membrane because is an antibiotic that alternates hydroxy and amino acid, ans it helps membranes to be permeable. Valinomycin is a cyclic molecule that helps in ions transportation through membranes. Also, antibiotics have a temperature range of activity, that's why it is sensitive to changes.
