Summary OCR A-Level Biology 5.4.4 Regulation of Blood Glucose

Regulation of Blood Glucose
Optimum blood
glucose level




Fall in blood glucose Rise in blood
level detected by α- glucose level
cells detected by α-cells




α-cells secrete β-cells secrete
glucagon into the insulin into the
blood blood




glucagon detected insulin detected by
by receptors on the receptors on the
liver cells liver cells




Liver cells convert Liver cells remove
glycogen to glucose glucose from the
and release glucose blood and converts
into the blood glucose to glycogen




Optimum blood
