Cellular Respiration

Front

What is Cellular Respiration?

Back

Cellular Respiration is a biochemical process in 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 Citric Acid Cycle (Krebs Cycle), and the Electron Transport Chain.

Front

What is Glycolysis?

Back

Glycolysis is the first stage of Cellular Respiration that occurs in the cytoplasm, where glucose is broken down into two molecules of pyruvate, producing a small amount of ATP.

Front

What occurs during the Citric Acid Cycle?

Back

During the Citric Acid Cycle, acetyl-CoA is oxidized, releasing carbon dioxide and transferring energy to electron carriers (NADH and FADH2) for the Electron Transport Chain.

Front

What is the role of the Electron Transport Chain?

Back

The Electron Transport Chain is the final stage of Cellular Respiration, where electrons from NADH and FADH2 are transferred through a series of proteins, leading to the production of a large amount of ATP and water.

Front

What is anaerobic respiration?

Back

Anaerobic respiration is a type of respiration that occurs without oxygen, resulting in the production of energy through processes like fermentation.

Front

What is the equation for Cellular Respiration?

Back

The equation for Cellular Respiration is C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + ATP.

Front

What are the products of Cellular Respiration?

Back

The products of Cellular Respiration are carbon dioxide, water, and ATP energy.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration does not require oxygen and produces less ATP.

Front

What is the significance of ATP in Cellular Respiration?

Back

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