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 is the main energy currency of the cell?

Back

ATP (Adenosine Triphosphate) is the main energy currency of the cell, used to power various cellular processes.

Front

What is the role of glucose in cellular respiration?

Back

Glucose is a simple sugar that serves as the primary fuel for cellular respiration, providing the energy needed for ATP production.

Front

What are the three main stages of cellular respiration?

Back

The three 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 produced during glycolysis?

Back

Glycolysis produces 2 ATP molecules, 2 NADH molecules, and 2 pyruvate molecules from one glucose molecule.

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 take place?

Back

The Krebs Cycle takes place in the mitochondrial matrix.

Front

What is the role of NADH in cellular respiration?

Back

NADH is an electron carrier that transports electrons to the Electron Transport Chain, where it helps produce ATP.

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 generate ATP.
