Introduction: Oxygen is essential for cellular respiration and energy production in cells. The concentration of oxygen outside the cell is generally higher compared to inside the cell due to various factors such as diffusion, cellular respiration, and oxygen consumption.

Factors affecting oxygen concentration:
1. Diffusion: Oxygen molecules move from an area of higher concentration to an area of lower concentration until equilibrium is reached. This process occurs through the cell membrane, allowing oxygen to enter the cell from the surrounding environment.
2. Cellular respiration: Cells utilize oxygen during cellular respiration to produce energy in the form of ATP. This process occurs inside the cell and leads to a decrease in oxygen concentration inside.
3. Oxygen consumption: Oxygen is consumed by various cellular processes, such as oxidative phosphorylation, which occurs in the mitochondria. This consumption further reduces the oxygen concentration inside the cell.

Will the oxygen concentration inside and outside change with time?
Yes, the oxygen concentration inside and outside the cell will change with time due to the factors mentioned above. However, the direction of change may vary depending on the cellular activity and the surrounding environment.

Where will the oxygen concentration increase?
The oxygen concentration will increase outside the cell in areas where there is a higher concentration of oxygen. This can occur through processes such as diffusion, where oxygen molecules move from areas of higher concentration (e.g., the atmosphere or surrounding tissues) to areas of lower concentration (e.g., the cell).

Why will the oxygen concentration not change?
The oxygen concentration inside the cell may not change significantly if the rate of oxygen consumption by cellular processes is balanced by the rate of oxygen diffusion and supply from the surroundings. This equilibrium is necessary to maintain the required oxygen levels for cellular functions.

Conclusion: The concentration of oxygen is generally higher outside the cell compared to inside due to diffusion and cellular respiration. While the oxygen concentration inside and outside the cell can change with time, it depends on factors such as oxygen diffusion, cellular respiration, and oxygen consumption. Maintaining a balance between these processes is crucial to ensure an adequate oxygen supply for cellular functions.

No,oxygen is not same because of the oxygen used to produce energy in cell by mitochondria by mixing with glucose it form energy and carbon dioxide after that only few amount of oxygen remain in cell.
