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 purpose of cellular respiration?

Back

The main purpose of cellular respiration is to produce ATP, which is the energy currency of the cell.

Front

What are the two main types of cellular respiration?

Back

The two main types of cellular respiration are aerobic respiration (requires oxygen) and anaerobic respiration (does not require oxygen).

Front

What is the equation for aerobic respiration?

Back

6O₂ + C₆H₁₂O₆ → 6CO₂ + 6H₂O + Energy (ATP)

Front

Where does glycolysis occur in the cell?

Back

Glycolysis occurs in the cytoplasm of the cell.

Front

What is the net gain of ATP from glycolysis?

Back

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

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 mitochondria of the cell.

Front

What is the Electron Transport Chain (ETC)?

Back

The Electron Transport Chain (ETC) is the final stage of cellular respiration where most ATP is produced, using electrons from NADH and FADH₂.

Front

How many ATP molecules are produced in the ETC?

Back

The Electron Transport Chain produces approximately 32-34 ATP molecules.
