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 are the main stages of cellular respiration?

Back

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

Front

Where does glycolysis occur?

Back

Glycolysis occurs in the cytoplasm of the cell.

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 is ATP and why is it important?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.

Front

What are the products of glycolysis?

Back

The products of glycolysis are 2 pyruvate molecules, 2 ATP, and 2 NADH.

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 a series of protein complexes in the inner mitochondrial membrane that transfer electrons and pump protons to create a proton gradient for ATP synthesis.

Front

How does temperature affect cellular respiration?

Back

As temperature increases, the rate of cellular respiration generally increases, up to a certain point, after which it may decrease due to enzyme denaturation.
