Cell Respiration

Cell Respiration

Convert chemical energy from glucose, fats and proteins into a usable form, ATP.

Oxidation

1. Addition of Oxygen

2. Removal of Hydrogen

3. Removal of Electrons

Decarboxylation

1. Removal of Carbon

Reduction

1. Removal of Oxygen

2. Addition of Electrons

3. Addition of Hydrogen

Electron Carriers

NAD+ and FAD

Mitochondria Structure

1. Inner membrane is folded - cristae, for high surface area and has proteins for hydrogen ions transport, ATP-synthase to make ATP and electrons carriers.

2. Intermembrane Space = Small, which allows a concentration gradient of H+ which makes them move back to the matrix through the ATP-synthase.

3. Matrix has enzymes for the Krebs Cycle.

4. Has its own DNA to make mitochondria work.

5. Has its own ribosomes for protein synthesis.
