Cellular Respiration

Front

What is the primary purpose of cellular respiration?

Back

The primary purpose of cellular respiration is to convert biochemical energy from nutrients into ATP (adenosine triphosphate), which is used as energy by cells.

Front

What are the main products of cellular respiration?

Back

The main products of cellular respiration are carbon dioxide (CO2), water (H2O), and ATP.

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

Where does glycolysis occur in the cell?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What are the three main stages of cellular respiration?

Back

The three main stages of cellular respiration are glycolysis, the Krebs cycle (citric acid cycle), and the electron transport chain.

Front

What is produced during glycolysis?

Back

During glycolysis, glucose is broken down into two molecules of pyruvate, producing a net gain of 2 ATP and 2 NADH.

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?

Back

The Krebs cycle takes place in the mitochondrial matrix.

Front

What is the significance of the electron transport chain?

Back

The electron transport chain is significant because it generates the majority of ATP during cellular respiration through oxidative phosphorylation.

Front

What is fermentation and how does it relate to cellular respiration?

Back

Fermentation is an anaerobic process that allows for the production of ATP without oxygen, occurring when cellular respiration cannot proceed due to lack of oxygen.
