yes
This process is called cellular respiration. During cellular respiration, organisms break down glucose with the help of oxygen to produce ATP, the energy currency of cells. This process occurs in the mitochondria of cells.
Oxygen and Carbon Dioxide
Aquatic organisms respirate by extracting oxygen dissolved in water through their gills or body surface. The oxygen is then delivered to their cells, where it participates in cellular respiration to produce energy. Carbon dioxide, a byproduct of respiration, is released into the surrounding water.
This process is called oxidative phosphorylation OR cellular respiration
The products of photosynthesis, such as glucose and oxygen, are used by other organisms as a source of energy. Glucose is a key source of energy for many organisms, including plants, animals, and bacteria. Oxygen is used by animals for respiration to produce energy.
Oxygen is the reactant needed for cellular respiration that is absent from the fermentation reaction. In the absence of oxygen, some organisms, like yeast, undergo fermentation to produce energy in the form of ATP.
Oxygen is essential for organisms to carry out cellular respiration, a process that produces energy for their survival. Carbon dioxide is a waste product of cellular respiration that organisms release into the environment. Plants use carbon dioxide during photosynthesis to produce glucose, which is a source of energy for them and other organisms.
The need for energy drives organisms to carry out cellular respiration, which uses oxygen to produce energy in the form of ATP. This consumption of oxygen by organisms in respiration is a key process in the oxygen cycle. Without this demand for oxygen to produce energy, the cycling of oxygen between the atmosphere and living organisms would not occur at the same rate.
Organisms which need oxygen are called aerobic organisms or aerobes. The oxygen is used in the process of respiration to release energy from food. Organisms which do not use oxygen in respiration are called anaerobic organisms or anaerobes. See: http://en.wikipedia.org/wiki/Aerobic_organism
The life-giving gas is oxygen. Oxygen is essential for the survival of most living organisms as it is used for cellular respiration to produce energy.
Cellular respiration is the process by which cells break down glucose to produce energy in the form of ATP. Aerobic respiration specifically refers to the type of cellular respiration that requires oxygen to produce ATP. In contrast, anaerobic respiration does not require oxygen.
Cellular respiration occurs in most living organisms, including plants, animals, and microorganisms. It is the process by which cells break down glucose and other organic molecules to produce energy in the form of ATP.
