Metabolism
building blocks
-
-
-
the building blocks can be used to make new structure, make ATP or be stored
-
energy production
-
-
Amino acids are not primarily for energy but account for 22% of the body's total fuel requirements (only used if necessary)
regulation of metabolism
-
regulation by insulin
the major hormone of the fed state, targeting muscle, liver and adipose tissue
-
how it works
after a meal, glucose levels rise (set point)
-
-
-
other hormones
-
epinephrine/adrenaline
increase glucagon while decreasing insulin, using storage molecules as fuel
-
-
-
-
types of metabolism
-
catabolism
breaking down large molecules into smaller ones, causing ATP release
the fed and fasted state
the fed state
the state after a meal where nutrient levels in the blood are high and the body's main goal is the store all the food/fuel for later
-
-
fasted state
the body's goal here is to maintain blood glucose levels by using the stored nutrients such as fats and glycogen
-
-
the liver can maintain circulating glucose levels by using its own glycogen storage to make and release glucose into the blood
it can also make glucose from glycerol, aa , pyruvate and lactate through gluconeogenesis
