Amylases

  • Amylases are produced in the mouth and pancreas (and secreted into the duodenum).
  • Amylases break down starch into smaller sugars.

Proteases

  • Proteases are a group of enzymes that decompose proteins into amino acids in the stomach and small intestine (with the enzymes in the small intestine being produced in the pancreas).

FAQs on Enzymes in Digestion - Biology for GCSE/IGCSE - Class 10

1. How do enzymes help in digestion?
Ans. Enzymes play a crucial role in digestion by breaking down large molecules of food into smaller, more easily absorbable nutrients. They help in speeding up the chemical reactions that occur during the digestion process.
2. What are some examples of enzymes involved in digestion?
Ans. Some examples of enzymes involved in digestion include amylase, which breaks down carbohydrates; protease, which breaks down proteins; and lipase, which breaks down fats.
3. Can enzyme deficiencies affect digestion?
Ans. Yes, enzyme deficiencies can affect digestion. For example, a lack of lactase enzyme can lead to lactose intolerance, where the body is unable to digest lactose found in dairy products, resulting in symptoms like bloating and diarrhea.
4. How are enzymes produced in the body for digestion?
Ans. Enzymes involved in digestion are produced by various organs in the body, such as the salivary glands, stomach, pancreas, and small intestine. These organs release enzymes to help break down food at different stages of the digestion process.
5. Are there any factors that can affect enzyme function in digestion?
Ans. Yes, factors such as pH levels, temperature, and the presence of inhibitors can affect enzyme function in digestion. Enzymes work best within specific pH and temperature ranges, and certain substances can inhibit or enhance their activity.
