Cellular Respiration in Detail

Front

Where does glycolysis occur?

Back

Cytosol (outside of the mitochondria)

Front

Why is cellular respiration considered aerobic?

Back

Because it requires oxygen.

Front

What is the function of ATP synthase?

Back

To create ATP in chemiosmosis.

Front

List the 5 stages of cellular respiration in order.

Back

Glycolysis, Link Reaction, Krebs Cycle, Electron Transport Chain, Chemiosmosis.

Front

What molecules pass high energy electrons into the electron transport chain?

Back

NADH & FADH2.

Front

What is glycolysis?

Back

The process of breaking down glucose into pyruvate, producing ATP and NADH.

Front

What is the Krebs Cycle?

Back

A series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen acts as the final electron acceptor in the electron transport chain.

Front

What is chemiosmosis?

Back

The movement of ions across a selectively permeable membrane, down their electrochemical gradient, which drives ATP synthesis.

Front

What is the Link Reaction?

Back

The conversion of pyruvate into acetyl-CoA, linking glycolysis to the Krebs Cycle.
