Pancreas has two major jobs: Digestion, and hormonal control of blood sugar levels
I. Releases pancreatic juice
• released into the duodenum (first part of the small intestine)
• is alkaline (the opposite of acid).
This neutralizes the acid that had been created by your stomach.
• contains lipases – enzymes which break down fats
• contains proteases – enzymes which break down proteins
• contains amylases – enzymes which break down carbohydrates
II. Pancreas’s endocrine cells release hormones
Hormones regulate your blood sugar levels.
When [blood sugar] too high -> pancreas releases insulin
causes muscle and fat cells to take in more sugar, so this decreases [blood sugar]
promotes glycolysis – conversion of sugar into ATP, also decreases [blood sugar]
makes liver store glucose as glycogen
When [blood sugar] too low -> pancreas releases glucagon
tells liver to break down glycogen into glucose, so this increases [blood sugar]
stops cells taking in more sugar, so this increases [blood sugar]
STOPS glycolysis, so sugar isn’t turned into ATP, so this increases [blood sugar]
