The diagram shows the second messenger model of hormone action involved in blood glucose regulation.
Which row in the table correctly identifies the Hormone that triggers this pathway in response to a fall in blood glucose concentration, Enzyme E, Molecule M, and Enzyme K?
| Hormone | Enzyme E | Molecule M | Enzyme K | |
|---|---|---|---|---|
| A | Insulin | Adenylate cyclase | Cyclic AMP (cAMPc\text{AMP}cAMP) | Glycogen synthase |
| B | Glucagon | Adenylate cyclase | Cyclic AMP (cAMPc\text{AMP}cAMP) | Protein kinase |
| C | Adrenaline | Phosphorylase | Glucose-1-phosphate | Protein kinase |
| D | Glucagon | Protein kinase | Cyclic AMP (cAMPc\text{AMP}cAMP) | Adenylate cyclase |
