Cellular Respiration

1
Cellular Respiration

• Chapter 7 pgs 126-143
• Food to energy

2
Harvesting Chemical Energy

• From photosynthesis we get carbohydrates
  (glucose)
• Cellular respiration Breaking down the
  carbohydrates (glucose) to make ATP
• Starts with glycolysis
• Glyco sugar
• Lysis breaking
• Breaking down sugars

3
What happens after Glycolysis?

• Chemicals can take one of two pathways
• Anaerobic (no oxygen present) fermentation
• Makes no ATP, but keeps the cycles going
• Aerobic respiration
• Makes a lot of ATP

4
Glycolysis

• 1 six carbon glucose broken down into 2 three
  carbon pyruvic acid molecules
• Happens out in the cytoplasm
