Cellular Respiration

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

Front

What is Glycolysis?

Back

Glycolysis is the first stage of cellular respiration that occurs in the cytoplasm, where glucose is broken down into two molecules of pyruvate, producing a small amount of ATP.

Front

What is the Krebs Cycle?

Back

The Krebs Cycle, also known as the Citric Acid Cycle, is the second stage of cellular respiration that occurs in the mitochondria, where pyruvate is further broken down to produce ATP, NADH, and FADH2.

Front

What is the Electron Transport Chain?

Back

The Electron Transport Chain is the final stage of cellular respiration that occurs in the inner mitochondrial membrane, where electrons are transferred through a series of proteins, leading to the production of 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 and water.

Front

What is the chemical equation for Cellular Respiration?

Back

The chemical equation is: C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP.

Front

What is anaerobic respiration?

Back

Anaerobic respiration is a type of respiration that occurs without oxygen, resulting in the production of less energy and byproducts like lactic acid or ethanol.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.

Front

What is the significance of ATP in Cellular Respiration?

Back

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