1. CELLULAR RESPIRATION

2. ENERGY Energy is the ability to do work – Cars running on fuel  Chemical Energy – Computers and light bulbs  Electrical Energy

3. Living organisms depend on energy, too. Sometimes, it is easy to see when we need energy Other times, it is not that obvious

4. All organisms obtain energy in different ways

5. Lipids Proteins Nucleic Acids Carbohydrates BIOMOLECULES

6. Provide quick burst of ENERGY Polymer – Long chain of sugar Monomer – Monosaccharide – Sugar – Glucose CARBOHYDRATES

7. Cellular Respiration is the process in which sugars (glucose) are converted into usable energy (ATP). Glucose is the fuel for Cellular Respiration WHAT IS CELLULAR RESPIRATION?

8. Cell Respiration happens in the Mitochondrion Outer Membrane Inner Membrane

9. Plant Cells REMINDER!!!!!! Animal Cells

10. Cellular Respiration needs: – Oxygen – Fuel/Energy Source Carbohydrates Sugars/Glucose REACTANTS FOR CELLULAR RESPIRATION

11. Cellular Respiration will produce: – Water – Carbon Dioxide – Energy/ATP PRODUCTS OF CELLULAR RESPIRATION

12. ATP is a molecule that provides the energy to a cell. Different parts of a cell uses ATP to carry their functions WHAT IS ATP?

13. GENERAL CHEMICAL REACTION Glucose (Sugar) Oxygen Water + + C 6 H 12 O 6 6O 2 6H 2 0++ + + ATP Cellular Energy Waste Products

14. A light bulb needs electricity to light up – Electricity is the energy A cell needs ATP to function – ATP is the energy ANALOGY

15. PHOTOSYNTHESIS AND CELLULAR RESPIRATION Glucose (Sugar) Oxygen Water + + C 6 H 12 O 6 6O 2 6H 2 0++ + + ATP Cellular Energy Water Glucose (Sugar) Oxygen + + Sunlight 6H 2 0 C 6 H 12 O 6 6O 2 ++ Sunlight
