Yes, insulin needs to be kept in the refrigerator, but not frozen.
no,becuse it has got enough sperm in it to keep it refrigirated
only use a insulin syringe for insulin. insulin MUST be correct.
No food contains insulin. Insulin is an hormone that is produced within the body. Diabetics that need to take insulin for their condition have to take it via injection.
Your pancreas knows how much insulin it needs to secrete if you take additional insulin insulin receptors in fat cells will become less responsive to it, so your pancreas will need to secrete more for the same effect. This process is the begining of type 2 diabetes. You would need to take additional insulin for a few weeks without any break for this to occure.
Insulin is a natural substance! It is made by your pancreas. If your pancreas is not making enough insulin to keep you alive, then you need to inject more insulin. There is nothing else except insulin that you can use.
Humans, who are not diabetic, make the insulin they need within their own bodies.
Eyes and the brain.
refrigerator
Nope
Most cell membranes are NOT permeable to sugar unless insulin opens a channel.
Every organ is made up of many cells and each of these cells need glucose for the provision of energy. Glucose molecules cannot enter the cells however unless they are each joined with a molecule of insulin. This is why the blood glucose is raised with diabetes. No insulin, then no glucose entering the cells. Hope this helps.
No you do not need to intake insulin if you do not have a certain disease in which your body does not receive insulin, such as diabtes. If you do not have diabetes then your body should be already making insulin.so no it is not a food source.(:
