Cellular Respiration AP

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 are the main stages of cellular respiration?

Back

The main stages are Glycolysis, the Krebs Cycle (Citric Acid Cycle), and the Electron Transport Chain (ETC).

Front

Where does glycolysis occur?

Back

Glycolysis occurs in the cytosol 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 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 oxidative phosphorylation?

Back

Oxidative phosphorylation is the process of ATP production that occurs in the mitochondria, using energy from electrons transferred through the ETC.

Front

What is the function of the Electron Transport Chain (ETC)?

Back

The ETC transfers electrons from NADH and FADH2 to oxygen, creating a proton gradient that drives ATP synthesis.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a cell membrane via specific transmembrane integral proteins.

Front

What happens to a substance that is oxidized?

Back

A substance that is oxidized loses electrons, which often results in an increase in its oxidation state.
