Cellular Respiration and Fermentation

1
Cellular Respiration and Fermentation
2
Cellular Respiration

• Using O2 to release energy stored in food
• O2 supplied by breathing
• Much of released Energy used to heat body

3
Reactants

• Sugar-C6H12O6
• O2

4
Products

• CO2
• H2O
• Energy in form of ATP

5
Formula

• Sugar-C6H12O6 6O2
• 6CO2 6H2O Energy (ATP)

6

• What is the difference between cellular
  respiration and breathing?

7
Relationship between Photosynthesis and Cellular
Respiration

• One big cycle

8
3 parts to Cellular Respiration

• Glycolysis Breaks C6H12O6 in two
  moleculescreates 4 ATP
• Kerbs Cycle Creates Charged particles for the
  next partReleases CO2
• Electron Transport Chain Sends charge particle
  down chain til O2Creates 32 ATP

9
Reaction Site

• In Bacteria (Prokaryote)-in the cell membrane
• In more complicated cells (Eukaryote)- mostly in
  the mitochondria

10
Fermentation

• Release of energy without O2
• Cell goes through Glycolysis only
• Must neutralize dangerous by products
• In Muscles-Lactic Acid
• In Yeast-released as CO2
