Quick explanation
Explain (HT only) that glucagon is secreted by the pancreas when blood glucose concentration is too low
- This point belongs to Hormonal coordination in humans, especially Control of blood glucose concentration.
- You need to be able to explain (HT only) that glucagon is secreted by the pancreas when blood glucose concentration is too low.
- The key ideas to know are pancreas, blood glucose, and HT only.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect Control of blood glucose concentration to exam-style questions, flashcards, and revision notes for Hormonal coordination in humans.
Quick student answer
How do you explain (HT only) that glucagon is secreted by the pancreas when blood glucose concentration is too low?
Direct answer
In Biology, this page helps you answer questions about (HT only) that glucagon is secreted by the pancreas when blood glucose concentration is too low within Hormonal coordination in humans. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are glucagon and pancreas.
Key terms
- glucagon: A hormone secreted by the pancreas that raises blood glucose levels by promoting the conversion of glycogen to glucose when blood glucose concentration is too low.
- pancreas: An organ that monitors and regulates blood glucose concentration by secreting hormones such as insulin and glucagon.
Common trap
Misunderstanding Glucagon's Role: Remember that glucagon is secreted when blood glucose is too low, stimulating the liver to convert glycogen back into glucose, while insulin is released when blood glucose is too high to facilitate glucose uptake by cells.
