∙ 14y agoOxygen is an extremely active element (with an electronegativity of 3.5, second only to fluorine) so oxidation reactions involving oxygen produce a lot of energy. Alternative metabolic pathways for getting energy from glucose without oxygen are simply less energetic.

∙ 11y agoIn the presence of oxygen, everything changes. The Kerbs cycle and electron transport enable the cell to produce 34 more ATP molecules per glucose molecule, in addition to the 2 ATP molecules obtained form glycolysis. This means that that 18 times as much ATP can be generated from glucose in the presence of oxygen. The final wastes of cellular respiration are water and carbon dioxide.

What does cellular respiration occurs in the presence of?
Generally it will occur in the presence of oxygen, which is aerobic respiration, but there are other times where no oxygen will be present and cellular respiration will occur anaerobically (fermentation). Aerobic respiration is more beneficial because you produce more ATP than anaerobically.
What type of food is produced by photosynthesis?
Photosynthesis uses light energy, water, and carbon dioxide to form glucose for the plant and oxygen as a waste product. 6CO2 + 6H2O + light energy ---> C6H12O6 + 6O2 Disregarding the light energy, coenzymes, and ATPs produced, the photosynthetic reaction is the exact reverse of the cellular respiration reaction.
How many molecules of ATP are produced by the entire breakdown of glucose?
I think that it is Mitochondria...but im not sure. The first stages in the breakdown of glucose occur in the cytoplasm of the cell. These reactions do not use oxygen and only a small amount of energy is converted to ATP. Much more energy is released in the second stage which does take place in the mitochondria. This is the stage which uses oxygen.
What organ does respiration occur in?
Virtually all oxygen using organisms have cellular respiration going on. C.R. is the breakdown of glucose using oxygen to release energy as ATP - so anything - plants, animals, single celled organisms - that take in oxygen and glucose are going to do CR. Organisms that can't tolerate oxygen or run out of oxygen (like your muscles during a strenuous workout) will do fermentation instead. Fermentation will get the job done but respiration releases much more energy per molecule of glucose.
What is the reactant and product in cellular respiration?
In the equation for cellular respiration the reactants, which go into the equation, are glucose and oxygen. The products, that come out of the equation, are carbon dioxide, water, and energy in the form of ATP.
Why can 18 times as much ATP be generated from glucose in the presence of oxygen than when oxygen in not available?
The Krebs Cycle and ETC enable the cell to produce 34 more ATP molecules per glucose. The 62 percent of the total energy of glucose that is not used to make ATP molecules is released as heat.
Cells produce ATP most efficiently in the presence of what molecule?
Oxygen. Cells can produce much more ATP from glucose in the presence of Oxygen (aerobic respiration) than without oxygen (anaerobic respiration) in a process called oxidative phosphorylation that occurs in the mitochondria of cells. In the presence of oxygen one glucose can be broken down to produce 36 ATP Without oxygen, only 4 ATP can be made
Why do yeast cells consume glucose much more slowly if oxygen is present than absent?
why do yeast cells consume glucose much more slowly when oxygen is present than when oxygen is absent
what substance do cells need to get energy from food?
When you become more active your cells need more oxygen and glucose, and when your body releases energy, glucose or other organic fuels in the presence of air is called aerobic respiration. aerobic respiration is in the absence of air.
How do you get energy fast?
When you are exercising you use your energy up and that's why you breathe fast but in order to get more energy you need more oxygen and glucose. To get more oxygen you need to breathe faster and to get more glucose you need to eat or drink something containing sugar, because glucose is a sugar.
What is the numberof glucose on the periodic table?
There isn't an atomic mass or number for glucose. Glucose is a compound of 6 Carbon, 12 Hydrogen, and 6 Oxygen atoms. Any more info requires more knowledge in this subject that I don't possess.
Do The products CO2 and H20 contain more energy than does the reactant glucose?
they are they same. the products of photosynthesis are oxygen and glucose and the reactants of cellular respiration are gluose and oxygen.
Does unit of fat take more oxygen to be converted to energy than glucose?
yes

Why your heart need lots of oxygen and glucose?
It is a large muscle which constantly exercising your entire lifetime. However, the human brain requires even more glucose and oxygen. The brain consumes 20% of the energy available.
How many atoms of hydrogen and oxygen are in glucose?
There are 12 atoms of hydrogen in a particle of glucose
What reduces oxygen is ponds?
this is correct as the fish cause a bacteria to be generated as they are in a cramped environment. this bacteria saps oxygen from the fish, so the fish in the pond take more oxygen. then the plants take in more oxygen to try and compete so they can respire (not photosynthesize.
