: 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 in short answer?
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.
Why is cellular respiration important simple explanation?
The purpose of cellular respiration is simple:
it provides cells with the energy they need to function
. … Key point: Cellular respiration involves catabolic reaction in order to break down food into usable energy so that cells, and the living organisms that contain them, can survive and thrive.
What is respiration in simple words?
Respiration:
The act of inhaling and exhaling air in order to exchange oxygen for carbon dioxide
.
How does cellular respiration work in humans?
Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell
uses oxygen to break down sugar
. … When the cell uses oxygen to break down sugar, oxygen is used, carbon dioxide is produced, and energy is released.
How does cellular respiration work simple?
Cellular respiration is the process by which organisms
use oxygen to break down food molecules to get chemical energy for cell functions
. … In the absence of oxygen, cells can get energy by breaking down food through the process of fermentation, or anaerobic respiration.
What is an example of cellular respiration?
Oxygen is used in cellular respiration. … For example, the
monosaccharide glucose
, (the most basic form of carbohydrate) can be combined with oxygen. The high energy electrons that are found in the glucose are transferred to the oxygen and potential energy is released. The energy is stored in the form of ATP.
Where does cellular respiration occur?
While most aerobic respiration (with oxygen) takes place in
the cell’s mitochondria
, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.
Who uses cellular respiration?
Organisms from all kingdoms of life
, including bacteria, archaea, plants, protists, animals, and fungi, can use cellular respiration.
What is the advantage of cellular respiration?
A major advantage of aerobic respiration is
the amount of energy it releases
. Without oxygen, organisms can just split glucose into two molecules of pyruvate. This releases only enough energy to make two ATP molecules. With oxygen, organisms can break down glucose all the way to carbon dioxide.
What is the most important aspect of cellular respiration?
Cellular respiration sustains aerobic life and involves
the oxidation of nutrients
, with the final production of carbon dioxide and water. During this process, oxidation energy is captured in the form of adenosine triphosphate (ATP) molecules.
What is the most important part of cellular respiration?
Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is
ATP
; waste products include carbon dioxide and water.
What is respiration give an example?
Respiration is taking a breath or the act of breathing. An example of respiration is
inhaling and exhaling air
. The action or process by which an organism without lungs, such as a fish or plant, exchanges gases with its environment.
What exactly is respiration?
Respiration is
a chemical reaction that happens in all living cells
, including plant cells and animal cells. It is the way that energy is released from glucose so that all the other chemical processes needed for life can happen. Do not confuse respiration with breathing (which is properly called ventilation).
Why is respiration so important?
The main purpose of respiration is
to provide oxygen to the cells at a rate adequate to satisfy their metabolic needs
. This involves transport of oxygen from the lung to the tissues by means of the circulation of blood.
