Why does fat digestion slow down greatly if the duct from the gall bladder is blocked?

Q: How do I try a free WJEC Biology question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live WJEC GCSE Biology bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for WJEC Biology students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Biology questions aligned to the WJEC GCSE syllabus?

Every question is written against the published WJEC GCSE Biology syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real WJEC past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

Why does fat digestion slow down greatly if the duct from the gall bladder is blocked?

Accepted Answer

Fat stays in large droplets, so there is less surface for lipase to act on — Award 1 mark. The fluid from the gall bladder breaks fat into tiny droplets, and that increase in surface area is what lets the enzyme work quickly. Lipase is still produced by the pancreas, the pH problem is separate and partial, and absorption failure would follow digestion rather than cause the slowdown.

Answer

The small intestine becomes too acidic for any enzyme to work

Answer

Fat stays in large droplets, so there is less surface for lipase to act on

Answer

No lipase can be made while the duct is blocked

Answer

Fat can no longer be absorbed once it has been digested
