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

Where does glycolysis take place?

Back

Glycolysis takes place in the cytoplasm of the cell.

Front

What are the main products of glycolysis?

Back

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

Front

What is the role of NADH and FADH2 in cellular respiration?

Back

NADH and FADH2 are high-energy electron carriers that transport electrons to the electron transport chain.

Front

Where does the Krebs Cycle occur?

Back

The Krebs Cycle occurs in the mitochondrial matrix.

Front

What is produced during the Krebs Cycle?

Back

The Krebs Cycle produces ATP, NADH, FADH2, and carbon dioxide.

Front

How many ATP molecules are produced from one glucose molecule during glycolysis?

Back

2 ATP molecules are produced from one glucose molecule during glycolysis.

Front

What is the electron transport chain?

Back

The electron transport chain is a series of protein complexes in the inner mitochondrial membrane that transfer electrons and pump protons to generate ATP.

Front

What is the final electron acceptor in cellular respiration?

Back

The final electron acceptor in cellular respiration is oxygen, which combines with electrons and protons to form water.

Front

What is fermentation?

Back

Fermentation is an anaerobic process that allows for the production of ATP without oxygen, resulting in products like lactic acid or ethanol.
