Believe it or not, cyanide kills us by inhibiting active transport, to such an extent that substances can no longer be transferred across cell membranes. This is one example of a substance that stops the process of active transport dead in its tracks.
There are a huge number of ways that this can occur. Water can simply diffuse through the cell membrane through osmosis, while other substances diffuse through special channels in the cell membrane. Some substances have to be brought into the cell through active transport, which requires the use of ATP.
If you experience excessive fluid loss, through vomiting, diarrhea, or sweating, or if you take certain medications, you may be at risk for potassium deficiency. In addition, a diet that is high in sodium and low in potassium can negatively affect potassium status. The Standard American Diet (SAD), which is high in sodium-containing processed foods and low in fruits and vegetables, contains about two times more sodium than potassium. Many health experts recommend taking in at least five times more potassium than sodium. The symptoms of potassium deficiency include muscle weakness, confusion, irritability, fatigue, and heart disturbances. Athletes with low potassium stores may tire more easily during exercise, as potassium deficiency causes a decrease in glycogen (the fuel used by exercising muscles) storage.
I am not a doctor, but taking potassium and iodide pills without proper guidance from a healthcare professional may not be effective in reducing radiation exposure. Potassium iodide is specifically recommended for treating radioactive iodine exposure. It is important to consult a healthcare professional to determine the appropriate course of action in case of radiation exposure.
The process of taking in essential substances and emitting harmful substances differs from organism to organism, based on their cell type. But the basic principle underlying all these processes is the semipermeability of the plasma membrane.

active transport -taking anatomy and physiology II
The 2 methods of active transport are taking the energy and using the energy to where the cell is doing the work,the cell will transport what is needed and all us done.
For patients taking the kinds of diuretics that rob potassium from the body, physicians may recommend adding potassium-rich foods or drinks such as citrus fruits and juices to the diet. Or, they may suggest taking a potassium supplement.
Bananas do not contain enough potassium to cause a problem when taking Losartan potassium tablets. One should always consult their doctor with any medical concerns while taking medication.
Active transport is important for cell function as, various activities keep taking place such as manufacture of protein, fat, etc. For all these activities raw materials are needed which need to be transported to the various cell organelles. Also, the waste products too need to be transported out of the cell body.
Active transport is moving substance against its gradient so it requires an input of energy to achieve this. One example is Na K ATPase. This is a secondary active transporter that pumps 3x Na out of the cell for 2x K into the cell. There are so much more Na outside the cell and already a lot of K inside the cell so to push the molecules there is an expenditure of ATP to do this.
The two major parts of active transport are endocytosis and exocytosis. Endocytosis is taking material into the cell by means of infoldings in the cell membrane. There are two types of endocytosis: phagocytosis (large molecules) and pinocytosis (small molecules). Exocytosis is the release of materials from a cell. The vacuole membrane and the cell membrane fuse together and the contents are released.

Only some antibiotics can increase potassium in your body. Sulfamethoxazole/Trimethoprim (Septra or Bactrim) and pentamidine have been known to increase potassium levels. If you are not taking either of those, your antibiotics should no effect on your potassium. If you are taking one of these drugs and your potassium levels are already high, you should contact your doctor and see if he or she wants to change your antibiotic to a different one.
