• Location: Mitochondria
• Three Steps
– Glycolysis
•Breaks glucose (6-Carbon) into two smaller compounds (3-Carbon) and produces 2 ATP
•1 Glucose -- 2 pyruvic acid molecules
–The KREBS CYCLE!
•If oxygen is present (aerobic).. then it goes to the Krebs Cycle
•In this cycle, (3-Carbon) compound and Oxygen are converted to CO2, 2 ATP, and lots of high energy electrons
–The ELECTRON TRANSPORT CHAIN (ETC)
•High energy electrons (from Krebs) are passed through a chain producing LOTS + LOTS + LOTS of ATP (34)
–Summary
•Aerobic Respiration
•Cells must contain GLUCOSE, OXYGEN, and ENZYMES..
•to make ATP, CO2, H2O
–What if after glycolysis there is NO oxygen?
•Anaerobic conditions lead to ... Fermentation
– Alcoholic
– Lactic Acid
– Very little ATP
