Question

If the pH outside the cell decreases, would you expect the amount of amino acids transported into the cell to increase or decrease?

Short answer

If the pH outside the cell decreases, the transport of amino acids into the cell would increase.

Step-by-step solution

Step1. Introduction   

PH is the measure of the acidity or basicity of intracellular fluid. The pH plays a critical role in membrane transport and other intracellular processes. In an environment with the improper pH, biological cells may have compromised function. Therefore, pH is closely regulated in order to ensure proper cellular function, controlled cell growth, and normal cellular processes.

Step2. Explanation 

A decrease in pH means an increase in positively charged H+ ions, and an increase in the electrical gradient across the membrane. If the pH outside the cell decreases, the transport of amino acids into the cell would increase.
