What is cellular respiration and where does it take place?

Cellular respiration is the process in which cells break down glucose, release the stored energy, and use it to make ATP. The process begins in the cytoplasm and is completed in a mitochondrion. Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport.

Where does cellular respiration occur in the body?

Respiration happens in the cells of plants, animals and humans, mainly inside mitochondria, which are located in a cell's cytoplasm.

Why does cellular respiration take place in the mitochondria?

Cellular respiration takes place (mainly) in the mitochondria because it is the cell's "powerhouse". It is where the energy (ATP) is produced in the cell, and the process of cellular respiration is the way the cells form that energy.

What are the 3 main parts of cellular respiration?

Cellular respiration is a collection of three unique metabolic pathways: glycolysis, the citric acid cycle, and the electron transport chain.

What are the 4 stages of cellular respiration and where do they occur?

The cellular respiration process includes four basic stages or steps: Glycolysis, which occurs in all organisms, prokaryotic and eukaryotic; the bridge reaction, which stets the stage for aerobic respiration; and the Krebs cycle and the electron transport chain, oxygen-dependent pathways that occur in sequence in the ...

What does cellular respiration do?

Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.

What type of cellular respiration do humans perform?

Carbon dioxide is a byproduct of aerobic respiration in humans. Yes. When humans and other animals lack sufficient oxygen, they'll create ATP through a form of anaerobic respiration that produces lactic acid as a byproduct.

What is the cellular respiration formula?

Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O.

What type of respiration requires oxygen?

aerobic respirationType of cellular respiration that requires oxygen.

What time does cellular respiration occur?

Respiration is essential for all living organisms and this includes plants. If respiration stops in a plant it will die, so plants constantly respire during the day and through the night. Respiration is a different process to photosynthesis, which depends on sunlight and therefore takes place only during the day.

What part of the mitochondria does cellular respiration take place?

Mitochondria are organelles whose membranes are specialized for aerobic respiration. The matrix of the mitochondria is the site of Krebs Cycle reactions. The electron transport chain and most ATP synthesis rely on the compartments created by the inner membrane of the mitochondria.

What substances are used up as the reactants in cellular respiration?

During cellular respiration, the reactants—glucose (sugar) and oxygen—combine together to form new products: carbon dioxide molecules and water molecules. Adenosine triphosphate (ATP) is produced as the form of energy that can be used for other cellular processes.
