Final answer:
The net negative charge on the cystolic side of the membrane enhances the rate of glucose import into the cell by a uniporter.
Step-by-step explanation:
The statement is TRUE. The net negative charge on the cytosolic side of the membrane enhances the rate of glucose import into the cell by a uniporter. Glucose is transported into the cell through glucose transport proteins (GLUTs), which are facilitated diffusion carriers. These transport proteins utilize the concentration gradient of glucose to move it into the cell, and the presence of a net negative charge on the cytosolic side of the membrane helps to attract and facilitate the movement of positively charged glucose molecules.
