Glycolysis

• Happens in the cytoplasm (cytosol) of the cell• We put in 2 ATP to start the process• We make 4 ATP and break the glucose down

into 2 molecules of pyruvateSince we paid 2 ATP up front to start the process we onlyGained 2 ATP

From glycolysis we get- 2 ATP- 2 pyruvate- 2 NADH (goes to ETC)

Pyruvate now travels to the mitochondria

The Krebs Cycle / Citric Acid Cycle

• Occurs inside the mitochondria• Is an aerobic process, NEEDS OXYGEN to work• Breaks down the pyruvate into acetyl-CoA• Net yield of 2 ATP• Net yield of 6 NAHD & 2 FADH2 (this will help run the next

process)• Releases Carbon dioxide as waste

Electron Transport Chain• Final stage of Cellular

Respiration• Takes place in the

mitochondria• Electrons are released from

NADH & FADH2 as they pass through the inner mitochondrial membrane, as they go through electrons give up energy to create 28-32 ATP

• Hydrogen is also combined with Oxygen to form water

Net Yield of each process
