12.18 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 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 as waste.

Front

What is the role 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 Krebs cycle take place?

Back

The Krebs cycle takes place in the matrix of the mitochondria.

Front

What is the main function of the electron transport chain?

Back

The main function of the electron transport chain is to create a proton gradient for ATP synthesis.

Front

What is the net gain of ATP from one molecule of glucose during glycolysis?

Back

The net gain of ATP from one molecule of glucose during glycolysis is 2 ATP.

Front

What is the waste product of the Krebs cycle?

Back

The waste product of the Krebs cycle is carbon dioxide.
