U2 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 glycolysis?

Back

Glycolysis is the first stage of cellular respiration that breaks down glucose into pyruvate, producing a small amount of ATP.

Front

What are the main stages of cellular respiration?

Back

The main stages are glycolysis, the Krebs cycle, and the electron transport chain.

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

What is the electron transport chain?

Back

The electron transport chain is the final stage of cellular respiration where electrons are transferred through a series of proteins, leading to the production of ATP and water.

Front

What is the final product of glycolysis?

Back

The final product of glycolysis is pyruvate.

Front

What are the products of aerobic respiration?

Back

The products of aerobic respiration are carbon dioxide and water.

Front

How does photosynthesis differ from cellular respiration?

Back

Photosynthesis uses carbon dioxide and produces oxygen, while cellular respiration uses oxygen and produces carbon dioxide.

Front

What is ATP?

Back

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

Front

What role does oxygen play in cellular respiration?

Back

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