Control of Blood Glucose AQA A level Biology

Powerpoint presentation for a lesson introducing the hormonal control of blood glucose concentration. Written for AQA A-level biology but easily adapted.

Specification points covered:
The factors that influence blood glucose concentration.
The role of the liver in glycogenesis, glycogenolysis and
gluconeogenesis.
The action of insulin by:
• attaching to receptors on the surfaces of target cells
• controlling the uptake of glucose by regulating the inclusion of
channel proteins in the surface membranes of target cells
• activating enzymes involved in the conversion of glucose to
glycogen.
The action of glucagon by:
• attaching to receptors on the surfaces of target cells
• activating enzymes involved in the conversion of glycogen to
glucose
• activating enzymes involved in the conversion of glycerol and
amino acids into glucose.

Does not cover the role of adrenaline or the second messenger model.
