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

10. Glycolysis Occurs in all organisms in cytoplasm - glucose split
7/3/2019
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)
7/3/2019
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)

14. Aerobic Respiration Mitochondrion
7/3/2019
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
