RESPIRATION

Electron Transport Chain• Carbon Dioxide is Waste• Hydrogen atoms and electrons are

carried by Co-enzymes as potential energy producers

Electron Transport Chain

Electron Transport Chain

Oxidative Phosphorylation

• Oxygen= Final acceptor• Oxidises HYDROGEN• This allows the addition of Phosphate

to ADP

Substrate level phosphorylation and oxidative phosphorylation

Oxidative Phosphorylation is the process by which ATP is formed as electronsare transferred from NADH2 and FADH2 to molecular oxygen

by a series of electron carriers

34 out of a total of 38 ATP molecules are generated by oxidative phosphorylation at the electron transport chain during

the complete oxidation of one molecule of glucose

Oxidative Phosphorylation occurs at the electron transport chain where thepresence of molecular oxygen, as the terminal acceptor of electrons,

is essential for its operation

Respiration•

• Each molecule of ATP produces 30.6 kJ f energy. How many are produced in total? How energy efficient is respiration?

MITOCHONDRIA LOCATIONS

• Where would you find the cells with the most amount of mitochondria in them and why?
