Enzymes and Digestion Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what’s on both sides.
  • Make sure you understand the information on each card. If something’s unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It’s useful to remember specific examples to understand these concepts better.

What is the role of digestive enzymes?

Digestive enzymes break down large insoluble molecules into smaller soluble molecules so they can be absorbed into the bloodstream.

What do carbohydrases do?

Carbohydrases break down carbohydrates into simple sugars. For example, amylase breaks down starch into maltose, and maltase breaks down maltose into glucose.

Where are proteases produced and what do they break down?

Proteases are produced in the stomach, pancreas and small intestine. They break down proteins into amino acids.

What is the function of lipases?

Lipases break down lipids (fats) into fatty acids and glycerol. They are produced in the pancreas and work in the small intestine (duodenum).

How does bile assist in lipid digestion?

Bile emulsifies fats, breaking them into smaller droplets for a larger surface area for lipase to work, and neutralises stomach acid to provide alkaline conditions for enzymes in the small intestine.

Where is amylase produced and what is its substrate and product?

Amylase is produced by the salivary glands and pancreas. It breaks down carbohydrates (like starch) into simple sugars (like glucose).
