What is Metabolism?
|
-All chemical reactions that go on in cells
-When chemical bonds break, energy is released |
|
|
What is ATP?
|
is energy
|
|
|
How do you Direct measurer the amount of energy in food?
|
bomb calorimeter
|
|
|
Where is the energy source glycogen primarily stored?
|
liver and muscle
|
|
|
Where is the primary location of Glucose or lipids?
|
body fluids
|
|
|
Where is triglycerides primarily stored?
|
adipose tissue
|
|
|
Where is protein primarily stored?
|
muscle
|
|
|
What is fat storage and what does it require?
|
Storage of triglycerides in fat cells
Requires a supply of Glucose and Fatty Acids |
|
|
What is energy balance? and what are ways to shift energy balance?
|
Comparison of energy in & energy out
-Kcal from food = kcal expended Ways to shift energy balance -Consume fewer kcal -Use more kcal |
|
|
How many kcal= does it take to burn 1 pound of fat (adipose tissue)?
|
3500 kcal = 1 lb of adipose tissue
|
|
|
What are the equations to maintain, gain and loose weight due to Energy balance?
|
Energy in = Energy out
Weight maintenance Energy in > Energy out Weight gain Energy in < Energy out Weight loss |
|
|
What is Basal metabolism (BMR)?
and what % of energy does the body use to maintain this Components of Energy Expenditure? |
-(50-65%) is how much body uses of energy
-Energy to maintain life at rest -Similar to resting metabolic rate (RMR) |
|
|
what % of energy does the body use to maintain this Components of Energy Expenditure?
|
(30-50%)
|
|
|
What is the Components of Energy Thermic effect of food (TEF) ?
and what % of energy does the body use to maintain this Components of Energy Expenditure? |
-(10%)
Energy for digestion, absorption, transport, and storage of nutrients |
|
|
What is the Components of Energy Adaptive thermogenesis?
and what % of energy does the body use to maintain this Components of Energy Expenditure? |
-(variable; <10%)
-Adjustments such as cold environment, overfeeding, trauma |
|
|
What are Factors that affect BMR?
|
-Lean body mass (muscle, bone)
More LBM . . . higher BMR -Surface area Larger surface area, higher BMR Gender Men > women Temperature (fever) Physiological processes |
