|
2 types of metabolsim
|
anabolic
catabolic |
|
|
anabolic metabolism
|
fed state
building of molecules |
|
|
catabolic metabolism
|
breaking down of molecules
fasted state |
|
|
3 general nutrient types
|
fat
carb protein |
|
|
how does the Atkin diet work?
|
no carbs, high protein, high fat
works b/c w/o carb intake, there's no readily available store of glucose so body has to get it from fat and tissue |
|
|
ATP
|
adesnosine triposphate
fuels for all biological processes need to make it from food |
|
|
what molecule breaks down and becomes ATP and what is the process called
|
ATP
glycolysis |
|
|
1 molec of glucose makes how many ATP molecules anaerobically
|
2 ATP
|
|
|
1 molec of glucose makes how many ATP molecules aeorbially
|
30-36
|
|
|
economy of aerobic metabolism of fat
|
100 ATP/glucose
|
|
|
efficiency
|
energy produced per energy invested= net energy gain/energy used
|
|
|
efficiency of living systems
|
40%
|
|
|
main controller of glycogen stores
|
pancreas
|
|
|
insulin
|
produced in fed state
imp to take glucose into cells |
|
|
what doesn't need insulin
|
brain, kidneys, intestinal cells, exercising muscles
|
|
|
processes that insulin control
|
glycogensis, glucolysis, fat synthesis
|
|
|
glucagon
|
glycogen --> glucose in the liver
|
|
|
type I diabetes
|
immune system destroys insulin producing cells
|
|
|
type II diabetes
|
insulin resistant cells
|
|
|
metabolic rate
|
energy you burn/time
|
|
|
how to mesaure metabolic rate
|
O2 consumption
|
|
|
%O2 in air you breathe in
|
21%
|
|
|
%O2 in air you breathe out
|
16%
|
|
|
RMR
|
resting metabolic rate= baseling rate of energy use
|
|
|
Kleiber's Law- real and prediction
|
prediction = 0.66(RMR= M^0.66) --> SA
real x=0.75 the bigger you get, the lb per lb metabolic rate decreases cells of bigger animals are getting by with less everyday |
|
|
implication of Kleiber's Law
|
big animals can get away with foods that are energetically poor
|
|
|
Resistance is proportional to
|
(viscosity*L/ r^4)
|
|
|
Flow rate is proportional to
|
change in pressure/ R
|
