Honors Biology Chapter 9 Cellular Respiration

Front

What is cellular respiration?

Back

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

Front

What is the maximum number of ATP produced from one glucose molecule during aerobic respiration?

Back

38 ATP.

Front

What happens to ATP when energy is released?

Back

A phosphate group is removed from ATP, converting it to ADP (adenosine diphosphate).

Front

Which types of cells perform cellular respiration?

Back

All cells, including plant cells, animal cells, and bacterial cells.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen, while anaerobic respiration occurs without oxygen.

Front

What is glycolysis?

Back

Glycolysis is the first step of cellular respiration where glucose is broken down into two molecules of pyruvic acid.

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 end products of aerobic respiration?

Back

The end products of aerobic respiration are ATP, carbon dioxide, and water.

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.

Front

What is the citric acid cycle?

Back

The citric acid cycle (Krebs cycle) is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.
