Lesson 09: Energy from Organic Molecules II

what is the role of NADH and FADH2 in cellular respiration?

Carry electrons to the electron transport chain

What is the purpose of the Electron Transport Chain?

Pump H+ into the membrane space

What does ATP synthase do?

Generates ATP through oxidative phosphorylation

What happens if the electron transport chain is blocked?

the H+ gradient is reduced and ATP production is lessened

What is the final electron acceptor in Anaerobic respiration?

Inorganic molecules (not O2)

When CO2 is reduced to CH4 (methane), it is classified as…..

Anaerobic respiration

In fermentation, ______________ is only source of ATP

glycolysis

In what reduces organic molecules in order to regenerate NAD+

fermentation

What are the byproducts of fermentation?

CO2, ethanol, and NAD+

Where does lactic acid fermentation occur?

animal (muscle) cells

What are the key intermediates in oxidative respiration?

Pyruvate and acetyl-CoA

What is deamination?

Removal of amino group from Animo acids
