Energy Flashcards
1
Q
What is the first law of thermodynamics?
A
Energy can be transformed from one form to another but can not be created or destroyed.
2
Q
What is REE>
A
Resting energy expenditure
3
Q
What is DEE?
A
Thermic effect of food
4
Q
What is AIEE?
A
Physical Activity
5
Q
What is BMR?
A
Basal Metabolic Rate
- Energy expenditure at rest
- Energy expended to fulfill life sustaining function
- under strict conditions
6
Q
How does EER differ from BMR ?
A
EER is not under any strict conditions
7
Q
What is the Thermic Effect of Food?
A
Diet Induced energy expenditure
- Diet induced thermogenesis
- Energy needed for digestion and processing food
- 10% of energy
- varies with diet composition
8
Q
What is Physical Activity?
A
Activity induced energy expenditure
- PAL
- intensity and duration of physical exercise is a determinant
9
Q
What is positive energy balance ?
A
Energy in is greater than energy out, indicates growth
10
Q
What is negative energy balance?
A
Energy in is less than energy out, indicates weight loss
11
Q
What is energy balance ?
A
Energy in = energy out, for adults
