Q

Food

A
  • Carbohydrate : rice, noodles
  • Protein : animal, fish and eggs
  • Protein : plants, soybeans and peanuts
  • Fat/lipid : animal, butter
  • Fat/lipid : plants, avocado
15
Q

Energy transformation

A

Is the process of changing energy from one form to another. Energy transformation takes place in cell organelles

16
Q

Energy transformation by chlorophyll

A
  • Light energy is converted into chemical energy which is stored in carbohydrate/glucose molecules
  • Photosynthesis : Carbon dioxide + water, with the help of light, it produces carbohydrate/glucose + oxygen
  • This energy is used by plants for activities and is also used by other living things that consume these plants
17
Q

Energy transformation by mitochondria

A
  • Chemical energy is used to convert carbohydrate, protein, fats into chemical energy in the form of ATP (Adenosine Tri Phosphate)
  • ATP is an energy carrier molecules
