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

Front

What is the primary purpose of cellular respiration?

Back

The primary purpose of cellular respiration is to produce ATP, which is used as energy by cells.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Front

What is the equation for cellular respiration?

Back

The equation for cellular respiration is: oxygen + glucose → carbon dioxide + water + ATP.

Front

How does exercise affect breathing rate?

Back

During exercise, the breathing rate increases to supply more oxygen to the muscles and remove carbon dioxide.

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen is essential for the final stage of cellular respiration, where it acts as the final electron acceptor in the Electron Transport Chain.

Front

What is glycolysis?

Back

Glycolysis is the first step of cellular respiration that occurs in the cytoplasm, breaking down glucose into pyruvate and producing a small amount 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 in the mitochondria that produces electron carriers (NADH and FADH2) and ATP.

Front

What is the Electron Transport Chain?

Back

The Electron Transport Chain is the final stage of cellular respiration, occurring in the inner mitochondrial membrane, where ATP is produced using energy from electrons.
