Question

Cholera (call er uh) is a disease caused by Vibrio cholerae bacteria. Cholera gets into the body through contaminated water or food. Severe diarrhea from cholera can kill a person in just a few hours. Intestinal cells are fooled by the shape of the cholera toxin and let it into the cell. Next, the toxin causes the cell to eject its chloride ions outside the cell membrane. Soon, the cell has a lower concentration of chloride than the intestinal fluid. Which process could the cell use to eject the chloride?

Options:
a. Active transport
b. Osmosis
c. Facilitated diffusion
d. Exocytosis

Answer 1

The intestinal cells eject chloride ions, caused by the cholera toxin, through exocytosis.

Step-by-step explanation:

The process that the intestinal cells could use to eject the chloride ions outside the cell membrane is active transport. Active transport is a process that requires the cell to expend energy to move ions or molecules across the cell membrane against their concentration gradient. In this case, the intestinal cells use active transport to pump chloride ions out of the cell and into the intestinal fluid, creating a lower concentration of chloride inside the cell.

Cholera is an infection caused by Vibrio cholerae bacteria, which enters the body through contaminated water or food. When the cholera toxin enters intestinal cells, it causes the cells to eject chloride ions. This process is known as exocytosis, as the intestinal cell uses vesicles that merge with the plasma membrane to release the chloride ions into the intestinal lumen.
