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 three main stages of cellular respiration?

Back

The three main stages of cellular respiration are Glycolysis, the Citric Acid Cycle (Krebs Cycle), and Oxidative Phosphorylation.

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 in the process.

Front

What is produced during the Citric Acid Cycle?

Back

The Citric Acid Cycle produces ATP, NADH, FADH2, and carbon dioxide as byproducts.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the final stage of cellular respiration where ATP is produced using the energy from electrons transferred through the electron transport chain.

Front

Where does glycolysis occur?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What is the role of NADH in cellular respiration?

Back

NADH serves as an electron carrier, transporting electrons to the electron transport chain during oxidative phosphorylation.

Front

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

Back

Up to 38 ATP molecules can be produced from one glucose molecule during cellular respiration, depending on the efficiency of the process.

Front

What is the significance of the mitochondrial cristae?

Back

The mitochondrial cristae are the folds of the inner mitochondrial membrane that increase the surface area for the electron transport chain and ATP synthesis.

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.
