Energy Needs

• Each cell in the human body uses, on average,
  1,000,000 ATP molecules per second
• 100,000,000,000,000 cells in the human body
• Each human uses 1 x 1020 ATP/sec
• 100,000,000,000,000,000,000 ATP/sec

7
Cellular respiration

• C6H12O6 6O2 6 CO2 6H2O 36 ATP
• Photosynthesis

8
Cellular Respiration

• Breaking down food products (organic compounds)
• Heterotrophs and autotrophs
• Anaerobic respiration
• No 02
• Aerobic respiration
• With 02

Glycolysis

• Occurs in all organisms
• in cytoplasm - glucose split
• Converted to 2 pyruvic acid (pyruvate)
• Gain 4 ATP (-2 from the beginning)
• Gain 2 NADH from NAD

12
Fermentation

• Occurs after glycolysis if no O2 is present
  (anaerobic)
• No ATP gained
• Alcoholic Fermentation
• Bacteria and yeast - used to make beer, wine,
  bread, yogurt, sour cream
• Lactic Acid Fermentation
• Animal muscle cells
• Minor discomfort (burning sensation)

Aerobic Respiration

• Mitochondrion
• Release of energy from food in the presence of O2
• After glycolysis - 90 energy left
• Krebs cycle - named after Sir Hans Krebs
• Pyruvic Acid enters and ATP, NADH, and CO2 exits
