Cellular respiration is a vital process in all living organisms, providing energy for various biological functions. This process occurs in every cell and can be either aerobic or anaerobic, depending on the availability of oxygen. Respiration edexcel gcse biology covers both types of respiration and their importance in living systems.

Cellular respiration is the fundamental process that enables all living organisms to obtain energy from nutrients. This page provides a comprehensive overview of both aerobic and anaerobic respiration, their mechanisms, and their significance in biological systems.
Aerobic respiration is the primary method of energy production in most organisms. It occurs in the mitochondria of cells and requires oxygen to completely break down glucose, resulting in a significant energy yield.
Definition: Aerobic respiration is the process of breaking down glucose in the presence of oxygen to produce energy, carbon dioxide, and water.
The equation for aerobic respiration is:
Highlight: Glucose + Oxygen → Energy + Carbon Dioxide + Water (C₆H₁₂O₆ + 6O₂ → Energy + 6CO₂ + 6H₂O)
The circulatory system plays a crucial role in aerobic respiration by supplying cells with oxygen from the lungs and glucose from the small intestine, while also removing waste products.
Anaerobic respiration occurs in the absence of oxygen and takes place in the cytoplasm of cells. It produces less energy compared to aerobic respiration but can provide quick bursts of energy when needed.
Definition: Anaerobic respiration is the process of breaking down glucose without oxygen, resulting in the production of lactic acid in animals or ethanol and carbon dioxide in plants and fungi.
In animals, the equation for anaerobic respiration is:
Highlight: Glucose → Lactic Acid + Energy
In plants and fungi, the equation is:
Highlight: Glucose → Ethanol + Carbon Dioxide + Energy
Example: Anaerobic respiration in yeast cells is called fermentation and is used in the production of bread and alcoholic beverages.
The page concludes with a brief mention of cardiac output measurement, which is related to the body's ability to supply oxygen for respiration.
Definition: Cardiac output is the volume of blood pumped by the heart per minute and is calculated by multiplying stroke volume by heart rate.
Highlight: Cardiac Output = Stroke Volume × Heart Rate
This formula is essential for understanding how to calculate cardiac output A level Biology and assessing the efficiency of the circulatory system in supporting cellular respiration.
