Cellular Respiration Formative

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.

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.

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 the Electron Transport Chain?

Back

The Electron Transport Chain uses electrons from NADH and FADH2 to create a large amount of ATP through oxidative phosphorylation.

Front

What is the final electron acceptor in the Electron Transport Chain?

Back

The final electron acceptor in the Electron Transport Chain is oxygen, which combines with electrons and protons to form water.

Front

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

Back

A total of approximately 36-38 ATP molecules are produced from one molecule of glucose during cellular respiration.

Front

What is anaerobic respiration?

Back

Anaerobic respiration is a form of respiration that occurs without oxygen, resulting in the production of less energy and byproducts like lactic acid or ethanol.
