Cellular Respiration

Front

What is cellular respiration?

Back

Cellular respiration is a metabolic process that converts glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

Where does glycolysis take place?

Back

Glycolysis takes place in the cytoplasm.

Front

What are the end products of glycolysis?

Back

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

Front

What happens to the carbon atoms in glucose during cellular respiration?

Back

They are released as CO2.

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 lactic acid fermentation?

Back

Lactic acid fermentation is an anaerobic process that occurs in muscle cells when oxygen is scarce, converting glucose into lactic acid and ATP.

Front

What cells in the body may undergo lactic acid fermentation during exercise?

Back

Muscle cells.

Front

What is the Krebs cycle?

Back

The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

Where does the Krebs cycle occur?

Back

The Krebs cycle occurs in the mitochondrial matrix.

Front

What is the electron transport chain?

Back

The electron transport chain is a series of protein complexes located in the inner mitochondrial membrane that transfer electrons and pump protons to create a proton gradient.
