What is cellular respiration simple answer?
Cellular respiration is the process by which organisms use oxygen to break down food molecules to get chemical energy for cell functions. The energy released is captured in molecules of adenosine triphosphate, or ATP, which then supply it to fuel other cellular processes (see biochemistry).
What is the best definition of cellular respiration?
: any of various energy-yielding oxidative reactions in living matter that typically involve transfer of oxygen and production of carbon dioxide and water as end products Cellular respiration is a series of reactions, occurring under aerobic conditions, during which large amounts of ATP are produced.—
What is cellular respiration in 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.
What is cellular respiration and how does it occur?
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 is cellular respiration 7th grade?
Cellular respiration is a chemical process that enables organisms to convert food into energy. Plants carry out cellular respiration using the same chemical process that occurs in animals animals consume food only to get energy for the process of cellular respiration.
What is cellular respiration and fermentation?
Cellular respiration uses oxygen in the chemical reaction that releases energy from food. Fermentation occurs in an anaerobic or oxygen-depleted environment. Because fermentation doesn’t use oxygen, the sugar molecule doesn’t break down completely and so releases less energy.
How do you teach cellular respiration?
5 ways to make cellular respiration a more approachable topic
- Show the people behind the science. People love stories.
- Relate it to the real world. Telling the stories of the scientists behind the science is one way of ‘humanizing’ it.
- Seeing is believing.
- Make it stick with word-play.
- Use virtual lab simulations.
What is cellular respiration and why is it important?
Cellular respiration is important because it provides the energy for living organisms to perform all of the other necessary functions to maintain life. Most single-celled organisms, such as bacteria, do not require much energy and are able to survive on glycolysis and fermentation.
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.
What are the three processes of cellular respiration?
Respiration may be divided into three phases: (1) external respiration, (2) internal respiration, and (3) cellular respiration. In external respiration, or breathing, a plant or animal takes in oxygen from its environment and releases carbon dioxide.
What are facts about cellular respiration?
Cellular respiration allows cells to stock up on the energy they will need in the future, by transferring it to a carrier of energy called ATP . This is done during the chemical reaction as cellular respiration slowly takes energy from the molecule and send it to ATP. Cellular respiration moves electrons.
