Cellular Respiration Review

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What are the three main stages of cellular respiration?

Back

The three main stages are Glycolysis, Krebs Cycle (Citric Acid Cycle), and Electron Transport Chain.

Front

Where does glycolysis occur in the cell?

Back

Glycolysis occurs in the cytosol (cytoplasm) of the cell.

Front

What is the primary purpose of the Krebs Cycle?

Back

The primary purpose of the Krebs Cycle is to produce electron carriers (NADH and FADH2) and ATP from the breakdown of acetyl-CoA.

Front

What is the role of the Electron Transport Chain in cellular respiration?

Back

The Electron Transport Chain is responsible for producing the majority of ATP during cellular respiration by transferring electrons through a series of proteins.

Front

What is chemiosmosis?

Back

Chemiosmosis is the movement of ions across a selectively permeable membrane, down their electrochemical gradient, which is used to generate ATP.

Front

What is the final electron acceptor in the Electron Transport Chain?

Back

The final electron acceptor is oxygen, which combines with electrons and protons to form water.

Front

How much ATP is produced during glycolysis?

Back

Glycolysis produces a net gain of 2 ATP molecules.

Front

What is the mitochondrial matrix?

Back

The mitochondrial matrix is the innermost compartment of the mitochondria where the Krebs Cycle takes place.

Front

What is the significance of NADH and FADH2 in cellular respiration?

Back

NADH and FADH2 are important electron carriers that transport electrons to the Electron Transport Chain, facilitating ATP production.
