Where does cellular respiration occur in a cell and why is it important?
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.
What does a cell need for respiration?
Glucose and oxygen react together in cells to produce carbon dioxide and water and releases energy. The reaction is called aerobic respiration because oxygen from the air is needed for it to work.
What are the main inputs of cellular respiration?
The inputs, or reactants, of cellular respiration are glucose and oxygen. The outputs, or products, of cellular respiration are water, carbon dioxide…
How will you describe cellular respiration in your own words?
Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP. This process releases carbon dioxide and water as waste products. 8. Plants have mitochondria and can perform cellular respiration.
Which of these does cellular respiration do quizlet?
Cellular respiration is the process by which living things convert oxygen and glucose to carbon dioxide and water, thereby yielding energy.
What would happen to the process of cellular respiration if there was no oxygen quizlet?
If there is no oxygen in the cell, it needs more of that NAD+ to keep the glycolysis process going. Fermentation frees up some NAD+ which happens to create byproducts.
What type of reaction is cellular respiration quizlet?
Describe the process of cellular respiration. It is the process that releases energy by breaking down food molecules in the presence of oxygen. The equation is: oxygen + glucose → carbon dioxide + water + energy.
What does cellular respiration always release quizlet?
Cellular respiration is the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen.
Where does cellular respiration occur quizlet?
Cellular respiration takes place in mitochondria, which are often called the cell’s “powerhouses” because they make most of a cell’s ATP. Glycolysis splits glucose into two three-carbon molecules and makes two molecules of ATP. Glycolysis takes place in a cell’s cytoplasm and does not need oxygen.
Where in eukaryotic cells does cellular respiration take place quizlet?
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.
What is the equation of aerobic cellular respiration?
Aerobic respiration is the aerobic catabolism of nutrients to carbon dioxide, water, and energy, and involves an electron transport system in which molecular oxygen is the final electron acceptor. The overall reaction is: C6H12O6 + 6O2 yields 6CO2 + 6H2O + energy (as ATP).
What substances are used up in respiration?
During the cellular respiration, glucose and oxygen are the reactants during this process and the main product of this process is ATP, with waste products carbon dioxide and water. Therefore, the correct answer would be option B. O2 (oxygen) and C6H1206 (glucose).
What is the difference between respiration and breathing?
Breathing and respiration are two completely different but interrelated body processes which assist body organs to function properly. Breathing is the physical process of exchanging gases whilst respiration is a chemical process which takes place at a cellular level and produces energy.
