Oxygen has the second highest electronegativity of any element, second only to fluorine. Since it would be unusual to have fluorine in the electron transport chain, we can safely expect that oxygen will have the highest electronegativity in the chain.
Most matter doesn't exist as individual atoms. Inert or "noble" gasses like helium and argon excepted, most matter exists in molecules that are composed of two or more atoms. Even pure oxygen isn't individual atoms; oxygen is the O2 molecule composed of TWO oxygen atoms. Except within the cores of stars, hydrogen, the most common element, normally exists as the H2 hydrogen molecule. So in general, matter is composed of molecules, which are composed of atoms.
11 atoms of oxygen, a total of near 50% of the mass of lactose.

Plenty of oxygen will provide your lungs with enough air to perform respiration. Plenty of oxygen will allow combustion to occur, allow oxidation to occur. Your question needs more detail. Respiration Respiration (or just breathing) means the transport of oxygen from the outside air to the cells within tissues, and the transport of carbon dioxide in the opposite direction.
No, oxygen therapy is only helpful when the problem is related to insufficient oxygen levels in the blood stream. Therefore, a disease like Alzheimer's, in which the problem is tangled proteins within neurons that cause the neurons to die, would not be responsive to oxygen therapy.
Hemoglobin is a metalloprotein, containing iron, that is within red blood cells and binds to gasses like oxygen in order to transport those gasses in the blood.
Hemoglobin carries oxygen to the body's tissues. It is found in erythrocytes.
Respiration is the transport of oxygen to cells within tissues and the transport of carbon dioxide in the opposite direction.
-central fatigue is feeling of tiredness and a desire to stop (protective mechanism) -insufficient release of acetylcholine from motor neurons -depletion of creatine phosphate -decline of Ca+2 within the sarcoplasm -insufficient oxygen or glycogen -buildup of lactic acid and ADP
When oxygen enters the bloodstream through the lungs it generally binds to red blood cells (more specifically the hemoglobin within red blood cells), which are carried along within the plasma. While some unbound oxygen may become diffused inside the plasma itself it is not the primary or intended mean of oxygen transport throughout the body. In short, plasma doesn't carry oxygen, but instead carries the cells that carry oxygen.
No, they are not. Microtubules for the basis of transport within the cell.
