Regulation of BLOOD GLUCOSE CONCENTRATION (OCR A-level Biology A)

This highly detailed, fully-resourced lesson has been designed to cover the content of specification point 5.1.4 (d) of the OCR A-level Biology A specification which states that students should be able to demonstrate and apply an understanding of the regulation of blood glucose concentration. There is focus on the negative feedback mechanisms that release insulin or glucagon and the role of the liver. It challenges the students recall of the control of insulin release from the beta cells which was taught in an earlier lesson.

A wide range of activities will maintain motivation and engagement whilst the content is covered in detail to enable the students to explain how the receptors in the pancreas detect the concentration change and how the hormones attaching to receptor sites on the liver triggers a series of events in this effector organ. This is a topic which has a huge amount of difficult terminology so time is taken to look at all of the key words, especially those which begin with the letter G so students are able to use them accurately in the correct context. The action of adrenaline is also considered and linked to the breakdown of glycogen to glucose during glycogenolysis.

This lesson has been written for students studying on the OCR A-level Biology A course and ties in with the lesson on the differences between type I and II diabetes mellitus as well as the human endocrine system
