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

Where does glycolysis occur?

Back

Glycolysis occurs in the cytosol of the cell.

Front

What are the main products of glycolysis?

Back

The main products of glycolysis are 2 pyruvate molecules, 2 ATP, and 2 NADH.

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 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 occur?

Back

Oxidative phosphorylation occurs in the mitochondrial cristae.

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.
