Cell Respiration

Front

What is cell respiration?

Back

Cell 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 cell respiration?

Back

The main stages of cell respiration are Glycolysis, the Krebs Cycle, and the Electron Transport Chain.

Front

What is the primary purpose of Glycolysis?

Back

The primary purpose of Glycolysis is to break down glucose into two molecules of pyruvate, producing a small amount of ATP and NADH.

Front

Where does Glycolysis occur in the cell?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What are NADH and FADH₂?

Back

NADH and FADH₂ are electron carriers that store energy used in the Electron Transport Chain.

Front

What is the role of ATP in cellular processes?

Back

ATP provides energy for various cellular processes, including muscle contraction, active transport, and biosynthesis.

Front

What is produced during the Krebs Cycle?

Back

The Krebs Cycle produces ATP, NADH, FADH₂, and carbon dioxide as waste.

Front

What is the starting molecule for the Krebs Cycle?

Back

The starting molecule for the Krebs Cycle is Acetyl-CoA.

Front

Where does the Electron Transport Chain take place?

Back

The Electron Transport Chain takes place in the inner mitochondrial membrane.

Front

What is the significance of oxygen in cell respiration?

Back

Oxygen is the final electron acceptor in the Electron Transport Chain, allowing for the production of ATP.
