AP Knowledge Check: 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 main stages of cellular respiration?

Back

The main stages of cellular respiration are glycolysis, the Krebs cycle (citric acid cycle), and oxidative phosphorylation (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 products of glycolysis are two molecules of pyruvate, two molecules of NADH, and a net gain of two ATP molecules.

Front

What is the role of NADH in cellular respiration?

Back

NADH acts as an electron carrier, transporting electrons to the electron transport chain for ATP production.

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 eukaryotic cells.

Front

What is the main purpose of the Krebs cycle?

Back

The main purpose of the Krebs cycle is to produce electron carriers (NADH and FADH2) and ATP, while releasing carbon dioxide as a waste product.

Front

What are the inputs of the Krebs cycle?

Back

The inputs of the Krebs cycle are acetyl CoA, NAD+, FAD, and ADP.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the final stage of cellular respiration where ATP is produced using the energy from electrons transferred through the electron transport chain.
