LO. Biology Organization of Living Things
Benchmark 3
Explain the process of food storage and food use
in organisms.
2
Carbohydrate
Fat
Protein
Nucleic Acid
3
Cellular Respiration

• Splitting glucose in the cytoplasm
• Burning food in the mitochondria when oxygen is
  present
• Releasing ATP energy
• Producing carbon dioxide as a waste product

4
Mitochondria
5
PHOTOSYNTHESIS

• Converting light energy into food
• Exciting electrons in chlorophyll to reduce
  Carbon dioxide to glucose (sugar)
• Using water to replace electrons in chlorophyll
• Giving off oxygen as a waste product

Key Concepts
Cellular respiration Photosynthesis Oxygen,
sunlight, carbon dioxide, carbohydrate, fat,
protein, minerals, water. How organisms
grow How plants store food How food and oxygen
are distributed to cells The sun as the ultimate
source of energy for organisms Energy
transformations
8
Real-world Contexts
Food storage such as maple treemaple sap,
potatostarch honey beehoney, cowbeef,
milk Weight gain and weight loss. Change in
respiration rates with exercise.

• 5. intake of carbon dioxide
• intake of oxygen
• 3-4-1
• 4-3-2
• 3-5-2
• D. 3-6-1
