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 glycolysis?

Back

Glycolysis is the first step of cellular respiration where one glucose molecule (6C) is split into two pyruvic acid molecules (3C), producing a small amount of ATP and NADH.

Front

What are NADH and FADH2?

Back

NADH and FADH2 are electron carriers produced during glycolysis and the Krebs cycle that transport electrons to the electron transport chain to generate ATP.

Front

What is the equation for cellular respiration?

Back

6O2 + C6H12O6 -> 6CO2 + 6H2O + Energy.

Front

Does glycolysis require oxygen?

Back

No, glycolysis does not require oxygen; it is an anaerobic process.

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 a large amount of ATP.

Front

What is the Krebs cycle?

Back

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

Front

How many ATP molecules are produced in glycolysis?

Back

Glycolysis produces a net gain of 2 ATP molecules per glucose molecule.

Front

What is the significance of the electron transport chain?

Back

The electron transport chain is crucial for producing the majority of ATP during cellular respiration by using electrons from NADH and FADH2.

Front

What are the end products of cellular respiration?

Back

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