Metabolism Lab Flashcards
body is basically a
biological consumption engine
car uses gas as
source of fuel
gasoline is injected into engine where
it is burned
pressure created by that burning fuel
propels the vehicle
what propels the body
digestive system
food is taken is as a source of
fuel
biological reactions then break down organic compounds in food to
create ATP which propel the body
when food is burned, biological energy is
converted to thermal energy (heat)
if you use thermal energy to heat a given volume of water, you can use the change in temperature to
calculate the energy of the food
a calorie is
unit of energy that measures how much energy food provides to the body
the body needs calories to
function properly
the amount of calorie in food gives you
energy, protein, carbohydrate, nutrients and fat to fuel your body
when you eat food your body turns the food into fuel burning it to produce
calories (energy)
the calories in your food come from
carbohydrates, proteins, fats
a gram of carbohydrate contains
4 calories
