<h2>Glucose production by liver</h2>
Explanation:
- Most of this secretory organ comprises of acinar or exocrine cells that discharge the pancreatic juice containing stomach related compounds, for example, amylase, pancreatic lipase, and trypsinogen, into the pipes, that is, the fundamental pancreatic and the extrapancreatic channel
- The endocrine cells are bunched together, along these lines shaping the supposed islets of Langerhans, which are little, island-like structures inside the exocrine pancreatic tissue that represents just 1–2% of the whole organ 
- drop in glucose triggers the arrival of glucagon by the pancreas. in the liver, glucagon enacts glycogen phosphorylase by animating its cAMP-subordinate phosphorylation and invigorates gluconeogenesis by bringing down [fructose 2,6 bisphosphate] consequently animating FB Pase-1
