1. Photosynthesis & Cellular Respiration

2. Key Concepts
Photosynthesis & Cellular Respiration are how ALL living things get energy from their environment
The reactants of photosynthesis are the products of cellular respiration
The reactants of cellular respiration are the products of photosynthesis

3. What is it? Photosynthesis Cellular Respiration
Photosynthesis uses radiant energy from the sun to convert carbon dioxide and water into glucose
Cellular Respiration converts glucose into ATP using oxygen

4. Who does it? Photosynthesis Cellular Respiration
Photosynthetic organisms are producers.
Producers make their own source of chemical energy.
Photosynthetic organisms are Plants, Algae, & Cyanobacteria
EVERY organism needs energy, so EVERY ORGANISM does cellular respiration!

5. Where does it happen? Photosynthesis Cellular Respiration Chloroplast
Chlorophyll, a pigment, absorbs the sunlight
It happens in the grana & the stroma
Mitochondria

6. More about Cellular Respiration…
Aerobic – oxygen is present Anaerobic – oxygen is not present
Lactic Acid Fermentation
A type of anaerobic respiration
Occurs when your cells don’t get enough oxygen to do regular aerobic respiration
Leads to lactic acid build up
