Energy & Nutrients Flashcards
What is energy measured in?
Joules.
What is Chemical Energy?
Form of energy found in the bonds that keep the atom of a molecule together.
What is Mechanical energy?
Form of energy related to motion.
What is Thermal Energy?
Form of energy caused by the motion of the particles in matter. (heat)
What is Radiant Energy?
Form of energy contained in light and other electromagnetic waves.
What is Thermal Energy used for?
Needed to heat organs, so they don’t shut down/die,
What is the Law of Conservation of Energy?
No energy can be lost or destroyed, energy can only be transformed or transferred into another type of energy.
What is Cellular Respiration?
C6 H12 O6 +6O2
The process by which oxygen and the food we eat , in the form of sugar (glucose) , is transformed into CO2 (a waste product we exhale), water, and energy (used by the body). = 6CO2+6H2O+energy
In Cellular Respiration, what is chemical energy transformed into?
Mechanical & Thermal Energy.
What is a Nutrient?
A chemical compound (such as protein, fat, carbohydrate, vitamin, or mineral) contained in foods. These compounds are used by the body to function and grow.
The energy value of a nutrient is the quantity of energy that the nutrient supplies to the body. This energy is measured in __________ ?
Kilojoules. (Calories)
Most of the energy comes from fats. 1g of fats supplies how many kilojoules?
37KJ of energy.
1g of carbohydrates or protein supplies how many kilojoules?
17KJ of energy.
What is the function of Carbohydrates?
Made up of starches & sugars, quickly transformed into energy by the body.
Where can you find Carbohydrates?
- Bread
- Pasta
- Rice
- Potato
What is the function of Fats?

Which is better for you? Saturated or Unsaturated fats?
Unsaturated fats.
What is the difference between saturated and unsaturated fats?
Saturated fats tend to come from animal-based products and can cause health problems if they’re eaten too much when compared to unsaturated fats which come from plants, and fish tend to have more benefits such as blood cholesterol levels, and ease inflammation.
