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 main stages of cellular respiration?

Back

The main stages 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 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 net gain of ATP from glycolysis?

Back

The net gain of ATP from glycolysis is 2 ATP molecules.

Front

What are the reactants of cellular respiration?

Back

The reactants of cellular respiration are glucose and oxygen.

Front

What are the products of cellular respiration?

Back

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

Front

What is the equation for cellular respiration?

Back

6O2 + C6H12O6 -> 6CO2 + 6H2O + Energy (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 is acetyl-CoA?

Back

Acetyl-CoA is a molecule that participates in many biochemical reactions in protein, carbohydrate, and lipid metabolism.
