Unit 5 Review

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 two main stages of cellular respiration?

Back

The two main stages are glycolysis and aerobic respiration (which includes the Krebs cycle and electron transport chain).

Front

What is glycolysis?

Back

Glycolysis is the first step of cellular respiration that occurs in the cytoplasm, breaking down glucose into pyruvate and producing a small amount of ATP.

Front

What is the Krebs cycle?

Back

The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions in the mitochondria that produces energy carriers (NADH and FADH2) and carbon dioxide.

Front

What is the electron transport chain?

Back

The electron transport chain is a series of proteins in the inner mitochondrial membrane that transfer electrons and pump protons to create a proton gradient for ATP production.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells, providing energy for various cellular processes.

Front

What are the reactants of the Krebs cycle?

Back

The reactants of the Krebs cycle are acetyl-CoA, water, and oxaloacetate.

Front

What are the products of cellular respiration?

Back

The products of cellular respiration are ATP, carbon dioxide, and water.

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

Where does glycolysis occur?

Back

Glycolysis occurs in the cytoplasm of the cell.
