Match the following clinical manifestations of lactose intolerance with their descriptions:

Bloating and flatulence = Undigested lactose in the colon becomes a substrate for fermentation by gut bacteria Diarrhoea = Unabsorbed lactose can draw water into the colon, leading to loose or watery stools Abdominal discomfort = The combination of fermentation, gas production, and the osmotic effect can cause abdominal discomfort and pain Nausea = Some individuals may experience nausea as a result of the digestive discomfort caused by lactose intolerance Signup and view all the answers

Match the following consequences of lactase deficiency with their effects:

Fluid osmotically driven into the intestine = Increases the volume and fluidity of the gastrointestinal contents Accumulation of gas in the colon = Leads to bloating and flatulence Unabsorbed lactose drawing water into the colon = Causing loose or watery stools Distension of the intestine due to gas and increased fluid content = Contributes to abdominal discomfort and pain Signup and view all the answers

Match the following gases produced during fermentation with their descriptions:

Carbon dioxide = Produced during fermentation of undigested lactose in the colon Methane = Produced during fermentation of undigested lactose in the colon Hydrogen = Produced during fermentation of undigested lactose in the colon Oxygen = Not produced during fermentation of undigested lactose in the colon Signup and view all the answers

Match the following severe symptoms of lactose intolerance with their descriptions:

Nausea = Some individuals may experience nausea as a result of the digestive discomfort caused by lactose intolerance Vomiting = In severe cases, the digestive distress may lead to vomiting Severe bloating = Feeling of extreme fullness and discomfort in the abdominal area Persistent diarrhoea = Unabsorbed lactose can draw water into the colon, leading to persistent loose or watery stools Signup and view all the answers

Match the following effects of unhydrolyzed lactose in the colon with their descriptions:

Osmotically driven fluid into the intestine = Increases the volume and fluidity of the gastrointestinal contents Fermentation by gut bacteria = Produces gases such as carbon dioxide, methane, and hydrogen Unabsorbed lactose drawing water into the colon = Causing loose or watery stools Distension of the intestine due to gas and increased fluid content = Contributes to abdominal discomfort and pain Signup and view all the answers

Study Notes

Chemistry in Various Industries

Chemistry contributes to food production by improving crop yields, creating fertilizers, and developing pesticides.
Chemistry impacts clothing production by providing synthetic fibers, dyes, and finishes that enhance fabric quality and durability.

Chemistry in Medicine

Chemistry research in medicine leads to the development of new medicines, vaccines, and diagnostic tools.

Chemistry in Transportation

Chemistry plays a role in transportation by providing fuels, lubricants, and materials for vehicle construction.

Adverse Effects of Chemical Processes

A potential adverse effect of chemical processes from industries is environmental pollution and harm to human health.

Lactose Intolerance and Fermentation

Symptoms of lactose intolerance include bloating, gas, diarrhea, and stomach cramps due to the body's inability to digest lactose.
Lactase deficiency leads to unhydrolyzed lactose in the colon, causing fermentation and resulting in gas, bloating, and diarrhea.
Gases produced during fermentation include hydrogen, methane, and carbon dioxide.
Severe symptoms of lactose intolerance include nausea, vomiting, and abdominal pain.
Unhydrolyzed lactose in the colon leads to an increased osmotic load, causing water to be drawn into the intestine, and resulting in diarrhea.
