A student in Jamaica measured the blood glucose level of a diabetic patient before and after eating a meal containing boiled green bananas and fried fish. The glucose level rose significantly and remained high for several hours. Which hormone is the patient's body failing to produce or respond to adequately?

Q: How do I try a free CXC Human and Social 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 CXC CSEC Human and Social 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 CXC Human and Social 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 Human and Social Biology questions aligned to the CXC CSEC syllabus?

Every question is written against the published CXC CSEC Human and Social 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 CXC past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Accepted Answer

Insulin — Award 1 mark for identifying insulin as the hormone that lowers blood glucose levels by promoting glucose uptake into cells. In diabetes, insulin is either not produced (Type 1) or cells do not respond to it (Type 2). A is incorrect — glucagon raises blood glucose. B is incorrect — adrenaline also raises blood glucose. D is incorrect — growth hormone is not directly responsible for lowering blood glucose after meals.
