Digestion/Absorption Flashcards
salivary amylase
breaks down carbs
Pepsin/HCL
-Break down food
-proteolysis
Main site of digestion/absorption of nutrients
Small intestine
3 parts small intestine (DJ puts music on, I dance)
duodenum, jejunum, ileum
secretin, CCK, bile, enzymes
chyme into SI
Absorbs water, electrolytes, makes SCFA & Vitamins
large intestine/colon
pyruvate
aerobic glycolysis
glycogen
-PPP
-glucose storage
-breakdown of carbs to glucose
-triggered by insulin
-MagnSIum, GlycolySIs
Glycolysis
lactate
-anerobic glycolysis (LACks O2)
-Cori cycle/muscles
transports glucose from blood-cell
insulin
-irreversible
-The Rich Ninja Painted My Library
pyruvate->acetyl CoA
-Makes NADH, FADH2
-starts Electron Transport Chain
Krebs Cycle
1 molecule of glucose
38 ATP
3 phases of metabolism
Glycolysis
Krebs
ETC
low blood glucose triggers
glycogenolysis
-prolonged fasting triggers
-FLAG
-ephiephrine & glucagon
-requires ATP
gluconeogenesis
-Proteins broken down to AA
-ammonia->urea
Deamination
-extra blood glucose after taken into cells
-creates triglycerides
lipogenesis
pyruvate turns into
Acetyl-CoA
How body neutralizes acid
Bicarbonate from kidneys
-Excess carbonic acid
-Blood gets more acidic
-COPH, asthma, holding breath
Respiratory acidosis
-kidney poor function
-shortage of bicarb
-diabetic ketoacidosis/diarrhea
Metabolic acidosis
-shortage of carbonic acid
-anxiety, panic attack, hyperventilation
respiratory alkalosis
-bicarb buildup
metabolic alkalosis
below 7.35
acidic
above 7.45
alkalosis
-genesis
-creates glucose
-lysis
breaks down glucose for use
Cholecystokinin
hormone release when fat enters small intestine
