Question

An experiment was conducted and the composition of the selectively permeable membrane was changed so that it became impermeable to carbon dioxide but remained permeable to oxygen. Explain how this manipulation will effect oxygen diffusion, carbon dioxide diffusion and muscle cell function?

Answer 1

This experiment is resulted in the following :

1. As, the semi permeable membrane become imperable to carbon dioxide, so it will stop the diffusion of carbon dioxide from the cells to the outside of the body for excretion. It will lead to the death of the cell.

2. As, the plasma membrane is permeable to oxygen, the diffusion of oxygen will occur from external environment to inside the body.  

3. Muscle cell function will be retarted because it will take oxygen necessary for ATP production but as during the exercise carbon dioxide is not released from the muscle because of the imperable nature to carbon dioxide will lead to the stopping of functions of the muscles.
