Oxygen burns hydrogen in the living system, releasing the energy that runs living beings.
Oxygen has the greater bond energy.
Energized oxygen is known as oxygen in an excited state (high energy). ... Excited state is when any atom/molecule (oxygen in this case) is not on ground state (most stable state). all atoms want to be on ground state because it is the most stable. In order to energize/ excite oxygen, energy has to be put in (for example, by the absorption of a photon of an appropriate energy). After excitation, all atoms want to return to ground state so they release the energy by emitting a specific energy. Excited oxygen is sometimes referred to singles oxygen while ground state oxygen is referred to as triplet oxygen, this is best explained by Molecular orbital theory.
The process of conversion of ozone into oxygen is a more spontaneous one than the conversion of oxygen into ozone. High amount of energy is released when ozone is broken down into oxygen. The reaction is as follows: 2O3 ---------> 3O2 + Energy
Facilitated diffusion.
aerobic
Cytosis requires energy, and the production of energy depends on oxygen. Diffusion does not require energy.
Nuclear Energy
The energy-releasing pathway that requires oxygen is aerobic respiration. This process involves the breakdown of glucose in the presence of oxygen to produce energy in the form of ATP. Anaerobic respiration and fermentation are energy-releasing pathways that occur in the absence of oxygen. Photolysis is a process that involves the splitting of water molecules using light energy during photosynthesis.
Most cellular energy comes in the form of ATP which requires oxygen.
The lactic acid energy system relies on the breakdown of glycogen to produce energy. As it does not require oxygen to break down glycogen a by-product called lactic acid is formed. If enough lactic acid is accumulated then the body begins to fatigue. To recover, the lactic acid requires oxygen. Once oxgen is present the lactic acid can be converted back to pyruvic acid which can once again be used to produce energy. Therefore to speed up recovery of the lactic system an "active"recovery at a low intencity is recommended. This then employs the use of the aerobic energy system which requires oxygen to be transported to the working muscles, and at the same time removing the fatiguing lactic acid.
the aerobic system is a long term energy system. It requires oxygen to ensure energy is available for the re-systhesis of ATP.It provides energy for low-moderate intensity exercise - 90 seconds plus ..... Goes through a number of chemical reactions - produces carbon dioxide and water
Cellulr respiration requires glucose and oxygen and produces carbon dioxide, water and energy
No. It is endothermic as it requires energy.
It is in respiration in aerobic reactions where it usually requires energy. It also requires water and oxygen. It occurs inside every cell to the formation of energy-rich ATP.
Cellulr respiration requires glucose and oxygen and produces carbon dioxide, water and energy
Exercising requires energy which requires oxygen to make. After the initial burst of energy is used up, not enough oxygen is being supplied to the heart so it then must work harder to pump blood. Therefore the lack of energy causes lack of oxygen causes heart to beat faster to compensate.
