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, the Krebs Cycle (Citric Acid Cycle), and the Electron Transport Chain.

Front

Where does glycolysis occur in the cell?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What is the end product of glycolysis?

Back

The end product of glycolysis is pyruvate.

Front

What is the role of pyruvate in cellular respiration?

Back

Pyruvate is a key intermediate that is converted into acetyl-CoA before entering the Krebs Cycle.

Front

What is the Krebs Cycle also known as?

Back

The Krebs Cycle is also known as the Citric Acid Cycle.

Front

Where does the Krebs Cycle take place?

Back

The Krebs Cycle takes place in the mitochondria of the cell.

Front

What are the main products of the Krebs Cycle?

Back

The main products of the Krebs Cycle are ATP, NADH, FADH2, and carbon dioxide.

Front

What is the function of NADH and FADH2 in cellular respiration?

Back

NADH and FADH2 are electron carriers that transport electrons to the Electron Transport Chain.

Front

Where does the Electron Transport Chain occur?

Back

The Electron Transport Chain occurs in the inner mitochondrial membrane.
