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 is the main purpose of cellular respiration?

Back

The main purpose of cellular respiration is to harvest energy from food.

Front

Which organisms perform cellular respiration?

Back

Both animals and plants perform cellular respiration.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, used to power various cellular processes.

Front

What are the main products of cellular respiration?

Back

The main products of cellular respiration are ATP, carbon dioxide, and water.

Front

What is the role of oxygen in cellular respiration?

Back

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

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration uses glucose and oxygen to produce ATP, carbon dioxide, and water.

Front

What is glycolysis?

Back

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

Front

What is the Krebs cycle?

Back

The Krebs cycle (or 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 is fermentation?

Back

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