The cholera bacterium makes a toxin. This toxin stimulates chloride ions to be secreted into the lumen of the small intestine. Why does this result in diarrhoea?
- AThe water potential in the lumen of the small intestine decreases and water moves into the small intestine by osmosis.
- BThe water potential in the lumen of the small intestine increases and water moves into the small intestine by osmosis.
- CThe water potential in the lumen of the small intestine decreases and water moves out of the small intestine by osmosis.
- DThe water potential in the lumen of the small intestine increases and water moves out of the small intestine by osmosis.
