Question 1 · 1 mark · Difficulty 1/3

Enzymes are biological catalysts, which means they:

  1. Speed up reactions without being used up
  2. Are used up in every reaction
  3. Slow down reactions
  4. Provide energy directly
Show answer & explanation
✓ Answer: ASpeed up reactions without being used up

Question 2 · 1 mark · Difficulty 2/3

The part of an enzyme where the substrate binds is called the:

  1. Active site
  2. Cell membrane
  3. Nucleus
  4. Ribosome
Show answer & explanation

AQA GCSE Biology: Enzymes and digestion FAQ

How many AQA GCSE Biology questions on Enzymes and digestion are there on Kramizo?
Kramizo currently has 15 exam-board-aligned practice questions on Enzymes and digestion for AQA GCSE Biology, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real AQA paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for AQA GCSE students preparing for Biology?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Enzymes and digestion practice with other Biology topics or even switch to a totally different AQA subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Enzymes and digestion questions aligned to the official AQA GCSE Biology syllabus?
Every question is written against the published AQA GCSE Biology specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real AQA paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from AQA.
How is Enzymes and digestion typically tested on AQA GCSE Biology papers?
Enzymes and digestion appears across multiple question types on real AQA GCSE Biology papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
