Cellular Respiration #2

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 of cellular respiration are Glycolysis, the Krebs cycle, and the Electron Transport Chain (ETC).

Front

Where does glycolysis occur in the cell?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What is the primary purpose of glycolysis?

Back

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

Front

What is produced during the Krebs cycle?

Back

The Krebs cycle produces ATP, NADH, FADH2, and carbon dioxide.

Front

Where does the Krebs cycle take place?

Back

The Krebs cycle takes place in the mitochondria of the cell.

Front

What is the role of NADH and FADH2 in cellular respiration?

Back

NADH and FADH2 are electron carriers that transport electrons to the Electron Transport Chain.

Front

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

Back

The function of the ETC is to use electrons from NADH and FADH2 to create a proton gradient that drives ATP synthesis.

Front

How many ATP molecules are produced in total from one glucose molecule during cellular respiration?

Back

Up to 38 ATP molecules can be produced from one glucose molecule during cellular respiration.

Front

What is the role of oxygen in aerobic cellular respiration?

Back

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