What is cellular respiration?

Back

Cellular respiration is the process by which cells use oxygen and carbon-based molecules from food to produce ATP, the energy currency of the cell.

Front

What is the primary energy currency of the cell?

Back

ATP (Adenosine Triphosphate) is commonly referred to as the energy currency of the cell.

Front

Which step of aerobic cellular respiration produces the most ATP?

Back

The electron transport chain produces the most ATP during aerobic cellular respiration.

Front

What process requires oxygen?

Back

Aerobic cellular respiration requires oxygen.

Front

In which stage of cellular respiration is carbon dioxide produced?

Back

Carbon dioxide is produced during the Krebs Cycle.

Front

What are the main stages of cellular respiration?

Back

The main stages of cellular respiration are glycolysis, the Krebs Cycle, and the electron transport chain.

Front

What is glycolysis?

Back

Glycolysis is the first step of cellular respiration that breaks down glucose into pyruvate, producing a small amount of ATP.

Front

What is the Krebs Cycle?

Back

The Krebs Cycle, also known as the citric acid cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

What role does oxygen play in cellular respiration?

Back

Oxygen acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP.

Front

What is fermentation?

Back

Fermentation is an anaerobic process that allows for the production of ATP without oxygen, resulting in byproducts like lactic acid or ethanol.
