TRANSCRIPT

9-2 The Krebs Cycle and Electron Transport

Pg. 226

A. The Krebs Cycle

• 1. During the Krebs cycle pyruvic acid is broken down into carbon dioxide.

• 2. Pyruvic Acid enters mitochondria and is broken down to citric acid.

Page 3: 9-2 The Krebs Cycle and Electron Transport Pg. 226

A. The Krebs Cycle

• 3. Citric acid is broken down and energy is released as ATP.

Make Connections!

• What happens to the carbon dioxide produced in the krebs cycle?

• Once, the carbon Dioxide leaves an organism what happens to it?

• Who benefits from the Carbon Dioxide in the air?

Page 5: 9-2 The Krebs Cycle and Electron Transport Pg. 226

B. Electron Transport

• 1. The electron transport chain uses high energy electrons from the krebs cycle to convert ADP to ATP.

C. The Totals

• 1. Glycolysis produces 2 ATP and requires no oxygen.

• 2. Krebs Cycle and Electron Transport Chain produces 36 ATP and requires oxygen.
