Pancreas Flashcards
What state are nutrients stored?
fed
what state are nutrients oxidized for energy production
fasting
broken down into sugar and is on the metabolic pathway of glycolysis
carbs
stored as glycogen or fat
carbs
broken down into fatty acids and glycerol with the metabolic pathway of Beta-Oxidation
Fats
stored as triglycerides in fat cells
Fats
Broken down into amino acids with the metabolic pathway of transamination
proteins
stored as glycogen or fat
proteins
a critical (and tightly
regulated) source of energy
glucose
the primary energy
substrate of
the brain.
glucose
Which portion of the pancreas is made of acinar and ductal cells
Exocrine portion
Produces and secretes digestive enzymes into intestines via pancreatic duct
Exocrine portion
What part of the pancreas is made of Islets of Langerhans (small
pockets of highly vascularized tissue
distributed throughout)
endocrine portion
Produces and secretes hormones
endocrine portion
What are the 3 cells that the Islets of Langerhans produces
Alpha cells
Beta cells
Delta cells
Released by alpha cells which leads to blood sugar increasing
alpha cell
Released by Beta cells which leads to a blood sugar decrease
insulin
an Anabolic Hormone
(energy storage)
insulin
target tissues of insulin
Target tissues: skeletal muscle, liver, and adipose tissue
increase of glucose uptake in tissues
insulin
increase in glucose storage
insulin
increase of fat synthesis
insulin
increase of protein synthesis
