Oxygen is used to break down energy which is then used in cells.
cells require oxygen to burn sugar.
No, water does not give cells oxygen. Oxygen is carried to cells by red blood cells in the bloodstream. Water is essential for various cellular functions, but it does not directly provide oxygen to cells.
The most basic need of a cell that oxygen can burn is energy production through aerobic respiration. Oxygen is used by cells to generate ATP (adenosine triphosphate) through a series of reactions, providing the energy needed for cellular functions and metabolism.
You don't lose it, you use it. Oxygen is used to burn the hydrogen of sugar and fats to generate the high energy phosphate bonds (ATP) that your cells need to do work. It's also used to "burn" the carbon in the fats and sugars, but you get no energy from that, only heat.
No. They just take oxygen from the air.

There is no oxygen in space, so spacecraft must carry oxygen with which to burn their fuel and, if they are manned, to allow the crew to breathe.

This process is called cellular respiration. It occurs in the mitochondria of cells and involves breaking down glucose (sugar) in the presence of oxygen to produce energy in the form of ATP (adenosine triphosphate).
Oxygen mixes with glucose through the process of cellular respiration to create energy in the form of ATP (adenosine triphosphate) in our cells. This process occurs in the mitochondria of cells and is essential for providing energy for various cellular functions.
Lungs are an important part of the respiratory system in our body and it is because of lungs that we can burn the energy in our bodies. The oxygen and carbon dioxide in lungs is carried in or out of them with the help of blood vessels. This means that the blood vessels carry the oxygen to the body from the lungs and the carbon dioxide do the opposite thing. The red blood cells present in blood carry these respiratory gases and if there is inadequate blood supply to the lungs then the gases will not be absorbed properly. If the absorption of gases is faulty then the body will be deprived of the ability to burn energy, ultimately life.
