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 used as energy by cells to perform various functions.

Front

What are the main stages of Cellular Respiration?

Back

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

Front

What is Glycolysis?

Back

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

Front

What is the Citric Acid Cycle?

Back

The Citric Acid Cycle, also known as the Krebs Cycle, is the second stage of cellular respiration that processes pyruvate to produce electron carriers and ATP.

Front

What is the Electron Transport Chain?

Back

The Electron Transport Chain is the final stage of cellular respiration where electrons are transferred through proteins to produce a large amount of ATP.

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 anaerobic respiration?

Back

Anaerobic respiration is a type of respiration that occurs without oxygen, producing less energy compared to aerobic respiration.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration does not require oxygen and produces less ATP.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, used to power various cellular processes.
