energy Flashcards
what is the 1st law of thermodynamics
energy can be transformed from one form to another but can’t be created or destroyed
what is our energy in coming from
food and beverages we eat
what is energy out from
heat lost (radiant and evaporation)
what is a direct measure of measuring energy expenditure
calorimetry
- siting in a room
what is a indirect measurement of energy expenditure
mask over the face
where does ATP come from in CHO
glucose
what is energy out (expenditure) come from
resting, thermic, physical, growth
what id Basal metabolic rate
energy expended at rest, fulfil life-sustaining functions, strict conditions
how much does muslce, liver and brain make up of BMR
60%
what is resting energy expenditure
energy expenditure at rest, fulfill life sustaining functions, no strict conditions - easier to measure
what does thermic effect of food stand for (DEE)
diet-induced energy expenditure
what is diet-induced energy expenditure
energy needed for digestion and processing of food,
how much energy does it take to digest food
10%
what does AIEE stand for
activity induced energy expenditure
if energy in is greater than energy out what type of energy is this and what does this mean
positive,
growth - weight gain
