AP Biology 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

What are the three main stages of cellular respiration?

Back

The three main stages of cellular respiration are Glycolysis, the Krebs Cycle (Citric Acid Cycle), and the Electron Transport Chain.

Front

Where does glycolysis occur?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What is the main product of glycolysis?

Back

The main product of glycolysis is pyruvate, along with a small amount of ATP and NADH.

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 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

What are the products of the Krebs Cycle?

Back

The products of the Krebs Cycle include ATP, NADH, FADH2, and carbon dioxide.

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 for ATP synthesis.

Front

How many ATP molecules are produced in the Electron Transport Chain?

Back

The Electron Transport Chain can produce approximately 32-34 ATP molecules per glucose molecule.

Front

What is fermentation?

Back

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