Unit 7: Cellular Respiration Flashcard

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 is the main purpose of the Electron Transport Chain (ETC)?

Back

The main purpose of the ETC is to produce ATP through oxidative phosphorylation by transferring electrons from NADH and FADH₂ to oxygen.

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen acts as the final electron acceptor in the Electron Transport Chain, allowing for the production of ATP.

Front

What are the three main stages of cellular respiration?

Back

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

Front

Where does glycolysis occur in the cell?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What is produced during glycolysis?

Back

Glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate molecules from one glucose molecule.

Front

What is the Krebs Cycle also known as?

Back

The Krebs Cycle is also known as the Citric Acid Cycle.

Front

What are the end products of the Krebs Cycle?

Back

The end products of the Krebs Cycle include 2 ATP, 6 NADH, 2 FADH₂, and carbon dioxide.

Front

What is anaerobic respiration?

Back

Anaerobic respiration is the process of producing energy without oxygen, resulting in products like lactic acid or ethanol.

Front

How does aerobic respiration differ from anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration does not require oxygen and produces less ATP.
