1. Cellular Respiration
The Energy in Food

2. The Energy in Food
Cellular Respiration – A chemical process that uses oxygen to convert the chemical energy stored in foods (sugars) into another form of energy (ATP)

3. Cellular Respiration

4. Photosynthesis / Cellular Respiration
Recycle a common set of chemicals:
Water
Carbon Dioxide
Oxygen
Glucose (Organic Compounds)

6. Reviewing the Mitochondria
Found in almost all Eukaryotic Cells (plants and animals)

7. Mitochondria
Matrix – the highly folded inner membrane enclosing a thick fluid Inner membrane- Folds inside the mitochondria

8. Respiration Two types of respiration: Aerobic (uses oxygen)
Anaerobic (without oxygen)
2 types of anaerobic respiration:
Lactic Acid Fermentation (Humans / Mammals)
Alcoholic Fermentation (yeast)

9. The Metabolic Pathways
Steps:
Glycolysis = 2 ATP
The Kreb Cycle = 2 ATP
3. Electron Transport Chain & ATP Synthase Action = 34 ATP
