Cellular Respiration Review

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 is the main purpose of cellular respiration?

Back

The main purpose of cellular respiration is to produce ATP, which provides energy for cellular activities.

Front

Where does cellular respiration occur in eukaryotic cells?

Back

Cellular respiration occurs in the mitochondria of eukaryotic cells.

Front

What are the three main stages of cellular respiration?

Back

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

Front

What is glycolysis?

Back

Glycolysis is the first stage of cellular respiration that breaks down glucose into pyruvate, producing a small amount of ATP.

Front

What is produced during the Krebs Cycle?

Back

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

Front

What role do NADH and FADH2 play in cellular respiration?

Back

NADH and FADH2 are electron carriers that transport electrons to the Electron Transport Chain, where ATP is produced.

Front

What is the Electron Transport Chain?

Back

The Electron Transport Chain is the final stage of cellular respiration where the majority of ATP is produced through oxidative phosphorylation.

Front

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

Back

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

Front

What gas is a byproduct of cellular respiration?

Back

Carbon dioxide is a byproduct of cellular respiration.
