The Astonishing Process of Cellular Respiration Explained

⚡️Cellular respiration is the process by which cells convert glucose and oxygen into ATP, carbon dioxide, and water.

🔥The process consists of three major steps: glycolysis, the Krebs cycle, and the electron transport chain.

🔄Glycolysis breaks down glucose into pyruvate, producing a small amount of ATP and NADH.

🎡The Krebs cycle further breaks down pyruvate, generating ATP, NADH, FADH2, and carbon dioxide.

⚡️The electron transport chain uses the electrons from NADH and FADH2 to create a proton gradient across the inner mitochondrial membrane, which is then used to generate ATP.

What is cellular respiration?

—Cellular respiration is the process by which cells convert glucose and oxygen into ATP, carbon dioxide, and water to produce energy.

What are the three major steps of cellular respiration?

—The three major steps of cellular respiration are glycolysis, the Krebs cycle, and the electron transport chain.

What is glycolysis?

—Glycolysis is the first step of cellular respiration, where glucose is broken down into pyruvate, producing a small amount of ATP and NADH.

What is the Krebs cycle?

—The Krebs cycle is the second step of cellular respiration, where pyruvate is further broken down to generate ATP, NADH, FADH2, and carbon dioxide.

What is the electron transport chain?

—The electron transport chain is the final step of cellular respiration, where NADH and FADH2 donate electrons, creating a proton gradient used to generate ATP.
