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. Which biomolecule are we mostly dealing with?
Lipids
Proteins
Nucleic Acids
Carbohydrates

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

7. What is cellular respiration?
Cellular Respiration is the process where sugars (glucose) are converted into usable energy ATP (Adenosine triphosphate).
Glucose is the fuel for Cellular Respiration
Cell Respiration happens in the…?
MITOCHONDRION

8. Plant Cells Animal Cells
Remember – Chloroplasts are found only in plant cells. Mitochondria are found in both plant and animal cells.
Plant Cells
Animal Cells

9. Reactants for Cellular respiration
Cellular Respiration needs:
Oxygen
Fuel/Energy Source
Carbohydrates
Sugars/Glucose

10. Products of Cellular Respiration
Cellular Respiration will produce:
Water
Carbon Dioxide
Energy/ATP

11. What is ATP?
ATP is a molecule that provides the energy (POWer) to a cell.

Gasoline provides that energy
A cell needs ATP to function
ATP is the energy
