Cellular Respiration and Fermentation

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells break down glucose and other organic molecules to produce ATP, the energy currency of the cell.

Front

What are the main stages of cellular respiration?

Back

The main stages of cellular respiration are Glycolysis, the Krebs Cycle (Citric Acid Cycle), and the Electron Transport Chain (ETC).

Front

Where does glycolysis occur in the cell?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What is the Krebs Cycle also known as?

Back

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

Front

Where does the Krebs Cycle take place in the mitochondria?

Back

The Krebs Cycle takes place in the matrix of the mitochondria.

Front

What is the primary purpose of the Electron Transport Chain (ETC)?

Back

The primary purpose of the Electron Transport Chain (ETC) is to produce the most ATP by transferring electrons through a series of proteins.

Front

What is fermentation?

Back

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

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 byproducts of cellular respiration?

Back

The byproducts of cellular respiration are carbon dioxide (CO2) and water (H2O).

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.
