improper functining or regulation of which of the following might lead to poor regulation of membrane permeability? 1.albumin 2.fibrinogen 3.platelets 4.lymphocytes 5.chloride ion levels
To determine which of the following might lead to poor regulation of membrane permeability, we need to identify the component involved in the regulation of membrane permeability.
The regulation of membrane permeability is primarily controlled by proteins called ion channels, which allow specific ions to pass through the cell membrane. Therefore, we can eliminate options 1 (albumin), 2 (fibrinogen), and 3 (platelets) as they do not directly regulate membrane permeability.
Now let's consider the remaining options, 4 (lymphocytes) and 5 (chloride ion levels). Lymphocytes are a type of white blood cell involved in the immune response and do not directly regulate membrane permeability. On the other hand, chloride ions play a crucial role in regulating membrane permeability.
Thus, the correct answer is option 5, chloride ion levels. Improper functioning or regulation of chloride ions can lead to poor regulation of membrane permeability.
