Oxygen is required for cellular respiration and is used to break down nutrients, like sugar, to generate ATP (energy) and carbon dioxide and water (waste). Organisms from all kingdoms of life, including bacteria, archaea, plants, protists, animals, and fungi, can use cellular respiration.
In this way, why must all organisms undergo cellular respiration?
Energy is produced. That energy is obtained from the food the organisms intake. Cellular respiration is the process through which the energy stored in food is converted into a form of energy(ATP), that is usable by the organisms. That is why, the living organisms perform cellular respiration.
can living things live without cellular respiration? Aerobic cellular respiration is the process by which the cells of a living organism break down food and turn it into the energy they need to perform their essential functions. The importance of aerobic respiration in living things cannot be underestimated. Without this process, no living thing would survive.
Additionally, what does not use cellular respiration?
The energy molecules obtained from plants are “burned” oxidized in cellular respiration to produce energy in the form of ATP. anaerobic respiration also known as fermentation takes place in some forms of bacteria and yeast. These organisms that do no use cellular respiration are limited in their energy production.
How do humans use cellular respiration?
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. Breaking down sugar produces the energy your body needs.

What affects cellular respiration?
We’ll first review what cellular respiration is, and then explore how three factors affect it: temperature, glucose availability, and oxygen concentration.
What organelle does cellular respiration occur?
mitochondria
What are the types of cellular respiration?
Cellular respiration is the process by which cells get their energy in the form of ATP. There are two types of cellular respiration, aerobic and anaerobic. Aerobic respiration is more efficient and can be utilized in the presence of oxygen, while anaerobic respiration does not require oxygen.
What are the products 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 are the advantages of cellular respiration?
Advantages of Aerobic Respiration This releases only enough energy to make two ATP molecules. With oxygen, organisms can break down glucose all the way to carbon dioxide. This releases enough energy to produce up to 38 ATP molecules.
How do you explain cellular respiration?
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 is ATP used for?
The Adenosine triphosphate (ATP) molecule is the nucleotide known in biochemistry as the “molecular currency” of intracellular energy transfer; that is, ATP is able to store and transport chemical energy within cells. ATP also plays an important role in the synthesis of nucleic acids.
How do the process of respiration occurs in living organisms?
All living organisms need a constant supply of energy. Respiration is the process of releasing energy through the breakdown of nutrients such as glucose. Aerobic respiration releases lots of energy from each glucose molecule by breaking it down completely into carbon dioxide and water.
Why do we need oxygen in cellular respiration?
Cellular respiration is the process cells use to make energy. Cells in our body combine glucose and oxygen to make ATP and carbon dioxide. Oxygen combines with the electrons and two hydrogen ions to make water. Lastly, the hydrogen ions flow through ATP synthase to make ATP.
What are the two types of fermentation?
The two most common types of fermentation are (1) alcoholic fermentation and (2) lactic acid fermentation. (1) Alcoholic fermentation : the type of fermentation in which ethyl alcohol is the main end product . This is very common in yeast (unicellular fungus) and also seen in some bacteria.
Do humans use cellular respiration?
Cellular respiration is a metabolic pathway that converts nutrients into energy (ATP) that organisms need to live. For aerobic cellular respiration to occur, oxygen has to be present. Humans and other animals obtain oxygen for cellular respiration through breathing.
Do Plants carry out respiration?
Plant cells respire the same way animal cells do, but respiration is only one part of the process. While both plants and animals carry out cellular respiration, only plants conduct photosynthesis to make their own food.
