AQA A Level Biology Paper 2 2025 Question Paper Pdf

Get the official AQA A-Level Biology Paper 2 question paper from the June 2025 series (7402/2), sat on Friday 13 June 2025 (morning). This is the exact examiner-set paper used in the live exam, featuring structured questions, data analysis, calculations, and extended-response tasks across key Biology topics.

The paper covers core AQA 7402 Paper 2 topics including respiration, homeostasis, gene expression, genetics, populations, ecology, and nervous coordination. For example, Question 1 tests respiration processes such as glycolysis and the electron transport chain (pages 2–3), while Question 2 focuses on homeostasis including blood glucose regulation and negative feedback (page 4–5, with a feedback diagram in Figure 1). Later sections include genetics and inheritance (Question 5, page 13), neurone structure and synaptic transmission (Question 6, page 14–15), and ecological investigations using choice chambers and chi-squared analysis (Question 7, pages 18–22).

The paper also includes real experimental and data-based questions such as calorimetry calculations (page 6), statistical testing (χ² table on page 21), and evaluation of gene therapy effectiveness using real-world data (Table 1 on page 9). This makes it ideal for mastering exam technique, applying knowledge to unfamiliar contexts, and improving data interpretation skills.
