1. Oxygen Uptake:
* Paramecium takes in oxygen directly from the surrounding water through its cell membrane.
* The thin, permeable membrane allows oxygen to diffuse from the higher concentration in the water to the lower concentration inside the cell.
2. Cellular Respiration:
* Inside the Paramecium, the oxygen is used in mitochondria for cellular respiration.
* This process breaks down glucose (sugar) to release energy in the form of ATP.
* Carbon dioxide (CO2) is produced as a waste product.
3. Carbon Dioxide Release:
* The carbon dioxide produced during cellular respiration diffuses out of the cell through the cell membrane.
* Again, it moves from a higher concentration inside the cell to a lower concentration in the surrounding water.
Important Note:
* Paramecium does not have specialized respiratory organs like lungs or gills.
* The entire cell surface is involved in gas exchange.
* The small size of Paramecium allows for efficient diffusion across its cell membrane.
