Chapter 2 Fed State Flashcards
Triglycerides are digested down to —— in the—–
Digested down to glycerol and three fatty acid in the small intestine
Complex carbohydrates are digested down to——– in the——-
Digested down to simple sugars(glucose) in the mouth and small intestines
Proteins are digested down to———- in the——-
Digested down to free amino acids in the stomach and small intestine
Glucose starts off absorbed in the intestinal lining and is absorbed by
Glucose enters the blood and induces the pancreas to secrete insulin
Triglycerides are free-floating fat in the intestines that are released to—-and get turned into—-
Released to circulatory system
Intestinal cells absorb free fatty acid and reassemble them as triglycerides into particles called chylomicrons
Proteins starting off in the intestines is turned into
Protein is turned into amino acids and the free amino acids into the blood
In the Fed state, absorption in the gut has what concentrations
⬆️ insulin
⬇️glucagon
What to tissues do not need insulin to absorb glucose and will continue to absorb available glucose at all times
The brain
Red blood cells
In the Fed state, what does the brain do
The brain uses glucose almost exclusively and burns most of it all the way to carbon dioxide and water
Glucose➡️Acetyl CoA➡️TCA➡️ CO2 and H2O Or ATP
In the Fed state, the red blood cells
The red blood cells use glucose almost exclusively but since they don’t have mitochondria they burn it only as far as pyruvate then converted to lactate
Glucose➡️puruvate➡️lactate
Muscles in the Fed state will do what
Glucose is absorbed into muscle only when insulin permits the entry
Muscle will use glucose when there’s plenty of it because glucose increases insulin and insulin is required to absorb glucose into the muscle
Active muscle burns glucose to
Aerobically - CO2
Glucose➡️Acetyl CoA➡️ TCA➡️CO2 and H2O or ATP
anaerobic-glucose ➡️lactate
Non active muscle :
Glucose ➡️Glycogen
Non-active muscle will do what with glucose
Stores glucose as glycogen when muscle is not being used
In the liver glucose is used
Glucose can freely enter and leave the liver that can only be used by the liver when insulin is high
It needs insulin in order to do something with the glucose
In the liver the amino acids
Amino acids are taken up so liver can produce its own proteins the excess amino acids are converted to fat
