Cellular Respiration (Overview)

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 oxidative phosphorylation.

Front

What is the input of glycolysis?

Back

The input of glycolysis is glucose.

Front

Where does glycolysis take place?

Back

Glycolysis takes place in the cytosol.

Front

What is the output of glycolysis?

Back

The output of glycolysis includes 2 pyruvate molecules, 2 ATP, and 2 NADH.

Front

What is the input of the Krebs cycle?

Back

The input of the Krebs cycle is acetyl CoA.

Front

Where does the Krebs cycle occur?

Back

The Krebs cycle occurs in the mitochondrial matrix.

Front

What is the main function of the Krebs cycle?

Back

The main function of the Krebs cycle is to produce electron carriers (NADH and FADH2) and ATP through the oxidation of acetyl CoA.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the final stage of cellular respiration where ATP is produced using the energy from electron transport and a proton gradient.

Front

Where does oxidative phosphorylation take place?

Back

Oxidative phosphorylation takes place in the mitochondrial cristae.
