what is necessary for respiration?

Aerobic 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. Energy is released in the reaction.

Aerobic respiration and fermentation are two processes which are used to provide energy to cells. In aerobic respiration, carbon dioxide, water, and energy in the form of adenosine triphosphate (ATP) is produced in the presence of oxygen. Fermentation is the process of energy production in the absence of oxygen.

Photosynthesis requires the products of aerobic respiration (carbon dioxide and water), while aerobic respiration requires the products of photosynthesis (glucose and oxygen). ... During respiration glucose is oxidised back to carbon dioxide, in the process, releasing energy that is captured in the bonds of ATP.
908726
In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.

Respiration is the chemical process by which oxygen from the lungs enters the blood and latches onto the red blood cells. Atmospheric air contains mainly Oxygen and Nitrogen. ... So we say we breathe in oxygen.

['During anaerobic respiration, the oxidation of glucose is incomplete - not all of the energy can be released from the glucose molecule as it is only partially broken down. ... ', 'glucose → lactic acid (+ ATP made)', 'The lactic acid is a waste product.', 'glucose → ethanol + carbon dioxide (+ ATP made)']

[' the structures through which gas exchange occurs must be thin so the diffusion can occur easily.', ' this membrane must be kept moist. ... ', ' to ensure enough exchange there must be a rich blood supply present ( 760 square feet)']

All organisms respire in order to release energy to fuel their living processes. The respiration can be aerobic, which uses glucose and oxygen, or anaerobic which uses only glucose.

The Atmosphere and Living Things Carbon dioxide and oxygen are the gases in the atmosphere that are needed for life. Plants need carbon dioxide for photosynthesis. They use sunlight to change carbon dioxide and water into food. The process releases oxygen.
901886
As respiration begins, glucose is broken down into pyruvic acid and two molecules of ATP are formed. ... Only anaerobic respiration occurs in the mitochondria. Only aerobic respiration requires oxygen. Only anaerobic respiration produces carbon dioxide.

Animal Respiration. Every cell in an animal requires oxygen to perform cellular respiration. Cellular respiration is the process by which animals take in oxygen and exchange it for carbon dioxide and water as waste products.
646970
Cellular respiration is the metabolic process in which cells obtain energy, usually by “burning” glucose in the presence of oxygen. ... Respiration by the respiratory system supplies the oxygen needed by cells for aerobic cellular respiration and removes the carbon dioxide produced by cells during cellular respiration.
1107999
In aerobic respiration, the main form of cellular respiration used by humans, glucose and oxygen are metabolized to release energy, with carbon dioxide and water as byproducts.

Nearly all cells respire, but far fewer cells do photosynthesis, therefore, by the standards stated, Respiration is more important. What cells undergo cellular respiration?

Cellular respiration is the cellular process which transfers chemical energy from glucose to ATP. Oxygen is essential to have efficient cellular respiration; most organisms need oxygen for a single purpose: to release energy from food for use by cells.

The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of the respiratory system are the lungs, which carry out this exchange of gases as we breathe.

Aerobic respiration Glucose is the molecule normally used for respiration - it is the main respiratory substrate . Glucose is oxidised to release its energy, which is then stored in ATP molecules.
