Cellular Respiration: The Location And Process Explained.

In order to understand cellular respiration, it is important to know where cellular respiration takes place and what the process entails. Cellular respiration takes place in the mitochondria of cells, and can be summarized as the breakdown of glucose to produce ATP (adenosine triphosphate). The process of photosynthesis requiring oxygen and giving off carbon dioxide is called “the war on one side.”

Cellular respiration is the process that takes place in the cells of our bodies to convert the food we eat into energy.

Stages of Cellular Respiration

The process of cellular respiration occurs in three stages: glycolysis, the citric acid cycle, and oxidative phosphorylation. The time of day and site where cellular respiration occurs can have an impact on the overall efficiency of this process.

First stage

Glycolysis is the first stage of cellular respiration and takes place in the cytoplasm of our cells.

Breakdown of Glucose Molecules

This process involves the breakdown of glucose molecules into two molecules of pyruvate.

Energy Released

The energy released from this process is used to generate ATP, which is essential for the cell to function.

Anaerobic Process

Glycolysis is an anaerobic process, which means that it does not require oxygen to occur.

Second Stage

However, the pyruvate molecules produced during glycolysis are typically oxidized in the second stage of cellular respiration, which is aerobic and does require oxygen.

Krebs cycle

The citric acid cycle, also known as the tricarboxylic acid cycle or the Krebs cycle, is a series of chemical reactions that take place in our cells.

Conversion into ATP

The cycle starts with the conversion of pyruvate into ATP, carbon dioxide, and water. ATP is used by cells for a variety of functions, including muscle contraction, nerve impulse conduction, and chemical synthesis

Third Stage

This is followed by the oxidative phosphorylation, which is the third stage of cellular respiration.


In this stage, ATP is converted into energy that can be used by our cells. The cycle ends with the production of carbon dioxide and water.

Important part of citric acid

The citric acid cycle is an important part of cellular respiration, as it provides the cells with energy.

Function Properly

Processes like respiration and photosynthesis are necessary for our cells to function.

Responsible for production

  • The cycle is also responsible for the production of carbon dioxide, which is a waste product that needs to be removed from our cells.
  • By understanding the citric acid cycle, we can better understand how our cells work and what happens when they don’t function correctly.
  • Cellular respiration is an important process that allows plants to convert the energy in food into usable energy for growth and development.
  • This process also helps to regulate plant metabolism and ensure proper cell function.
  • Additionally, cellular respiration helps plants to resist stressors such as drought and freezing temperatures.


Overall, cellular respiration is essential for plant health and vitality.

Useable Energy

Without this process, plants would be unable to convert the energy in food into usable energy, resulting in stunted growth and development.

Susceptible to stressors

Additionally, without cellular respiration, plants would be more susceptible to stressors such as drought and freezing temperatures. Consequently, it is clear that cellular.

The main difference between aerobic and anaerobic cellular respiration is that aerobic cellular respiration produces more ATP than anaerobic cellular respiration.

Aerobic cellular respiration also produces water as a by-product, while anaerobic cellular respiration produces lactic acid.

Cell Organelles

  • Cellular respiration takes place in the mitochondria of cells. Mitochondria are essential organelles in eukaryotic cells that play a vital role in energy production.
  • They are unique in that they possess their own DNA, which is distinct from the nuclear DNA of the cell.
  • This mitochondrial DNA encodes for proteins that are necessary for mitochondrial function. Mitochondria are also unique in that they can divide and replicate independently of the cell nucleus. Series of chemical Reaction
  • The process of cellular respiration is a series of chemical reactions that convert glucose and oxygen into water, carbon dioxide, and ATP. This process occurs in all living cells.

The structure and function of mitochondria are essential for understanding where does cellular respiration take place?

Location of Mitochondria

Mitochondria are organelles found in the cytoplasm of cells. They have a unique folded membrane that allows them to generate energy for the cell.


The process of cellular respiration takes place in the mitochondria, and it is responsible for generating ATP, which is the main source of energy for the cell.


Professional scientists have worked hard to uncover the mysteries of mitochondrial function, and there is still much to learn.

Cellular respiration is a necessary process in the food chain because it provides the energy that cells need to function. Organisms that rely on aerobic respiration for energy include animals, plants, and most bacteria
