Cellular Respiration

Front

What is cellular respiration?

Back

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

Front

What are the two main types of cellular respiration?

Back

Aerobic respiration (requires oxygen) and anaerobic respiration (does not require oxygen).

Front

What is the primary purpose of cellular respiration?

Back

The primary purpose of cellular respiration is to produce ATP, the energy currency of the cell.

Front

What is ATP?

Back

Adenosine triphosphate (ATP) is a molecule that stores and transfers energy within cells.

Front

What is glycolysis?

Back

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

Front

What happens during the citric acid cycle (Krebs cycle)?

Back

The citric acid cycle processes pyruvate to produce electron carriers (NADH and FADH2) and a small amount of ATP.

Front

What is the electron transport chain?

Back

The electron transport chain is the final stage of cellular respiration where electrons are transferred through proteins, generating a large amount of ATP.

Front

What is fermentation?

Back

Fermentation is an anaerobic process that allows cells to produce energy without oxygen, resulting in byproducts like lactic acid or ethanol.

Front

How does anaerobic respiration differ from aerobic respiration?

Back

Anaerobic respiration occurs without oxygen and produces less ATP compared to aerobic respiration, which requires 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.
