Just like in humans, radioactive material can damage plant tissues as well as inhibit growth. mutations are possible due to damage caused to the DNA. radioactive material in soil can prevent nutrient from being taken in by plants, causing it to be infertile.
Isn't it the cell membrane? The cell membrane controls what goes in and out of the cell using active and passive transport. Osmosis being a part of passive transport.
During intense exercise, there may not be enough oxygen available to complete the process, so a substance called lactate is made. Your body can convert this lactate to energy without using oxygen. But this lactate or lactic acid can build up in your bloodstream faster than you can burn it.
hope this helps :)
