Cellular Respiration Review

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells break down sugars to produce ATP, especially in the presence of oxygen.

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

What is the primary purpose of glycolysis?

Back

The primary purpose of glycolysis is to convert glucose into pyruvate, producing a small amount of ATP and NADH in the process.

Front

Where does glycolysis occur in the cell?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What are the end products of glycolysis?

Back

The end products of glycolysis are pyruvate, NADH, and a net gain of 2 ATP.

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 mitochondrial matrix.

Front

What are the main products of the Krebs cycle?

Back

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

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.

Front

Where does the electron transport chain occur?

Back

The electron transport chain occurs in the inner mitochondrial membrane.
