FINALS-WEEK 3

- Glycolysis

- requires oxygen

- End product is pyruvate

o Pyruvate has three carbons

• Aerobic

• Anaerobic

- Fermentation

- no need for oxygen

- End product is lactate

• Aerobic

• Anaerobic

o Lactate is converted to ______

acid which can cause acidosis

• lactic

• lactec

• lactin

- formation of two pyruvates

• Step 1 – Glycolysis

• Step 2 – Pyruvate oxidation

• Step 3 – Citric Acid Cycle

• Step 4 – Electron Transport System

- formation of two acetyl CoA

• Step 1 – Glycolysis

• Step 2 – Pyruvate oxidation

• Step 3 – Citric Acid Cycle

• Step 4 – Electron Transport System

- end product (oxaloacetate) combines

with acetyl CoA to start, forming the

same end product

- the energy produced during the cycle

will be used in the Electron Transport

System

• Step 1 – Glycolysis

• Step 2 – Pyruvate oxidation

• Step 3 – Citric Acid Cycle

• Step 4 – Electron Transport System

- use of high energy protons and electrons

(from coenzymes) to power ATP synthesis

• Step 1 – Glycolysis

• Step 2 – Pyruvate oxidation

• Step 3 – Citric Acid Cycle

• Step 4 – Electron Transport System
