Signalling molecule
Signalling molecule
Molecule that interacts with & initiates response in target cell
Hormone
Hormone
Signalling molecule from endocrine glands regulating target cells
Receptor
Receptor
Protein structure that detects a signal or external change
Target cell
Target cell
Cell that receives & responds to a specific signalling molecule
Lock & key mechanism (hormones)
Lock & key mechanism (hormones)
Hormones (keys) only fit specific receptors (locks) on cells
Endocrine system
Endocrine system
Glands producing hormones transported in blood to distant organs
Pituitary gland role
Pituitary gland role
'Master gland' controlling activity of other endocrine glands
Pancreas endocrine function
Pancreas endocrine function
Releases insulin & glucagon to regulate blood glucose levels
Alpha cells (pancreas)
Alpha cells (pancreas)
Produce glucagon which raises blood glucose levels
Beta cells (pancreas)
Beta cells (pancreas)
Produce insulin which lowers blood glucose levels
