Cellular Respiration

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 three main stages of cellular respiration?

Back

The three main stages of cellular respiration are Glycolysis, Krebs Cycle (Citric Acid Cycle), and Electron Transport Chain (ETC).

Front

Where does glycolysis occur?

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 as byproducts.

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 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 lactic acid fermentation?

Back

Lactic acid fermentation is an anaerobic process that occurs when oxygen is scarce, converting glucose into lactic acid and producing ATP.

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.

Front

What is the chemical equation for cellular respiration?

Back

The chemical equation for cellular respiration is: C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP.
