Glucose - Cell Metabolism

Glycolysis

• Breaking sugar

—> Breaks the sugar into pyruvate

—> Occurs in the cytoplasm and does not require oxygen

—> An anaerobic process

—> Generates 2 ATP and 2 NADH

Pyruvate Oxidation

• Prepping for the Powerhouse

—> Is the pyruvate from glycolysis

—> Where molecules of Acetyl-CoA are formed (since one carbon gets taken off each pyruvate molecule)

—> Forms 2 NADH as a by-product

Krebs Cycle (Citric Acid Cycle)

• The Energy Factory

—> Acetyl-CoA is essentially the fuel that the Cycle is burning to extract as much energy as possible to create things

—> A total of 2 ATP, 6 NADH, and 2 FADH2 moleCules are formed, along with some waste in the form of CO2

Oxidative Phosphorylation

• Big Energy Payoff

—> Electric Transport Train

—> The NADH and FADH2 act like full batteries, sending electrons through a special chain

—> With the aid of oxygen, hydrogen ions fall through the Electric Transport Train

—> Forms a total of 34 ATP and also some H2O

Outcome

• From one glucose molecule, you get lots of ATP
