No, therefore any excess amino acids are converted into fats and carbohydrates so they can be stored
Where are excess amino acids converted into fats and carbohydrates? What is a waste product?
Liver

Poisonous
Liver
Kidneys
Bladder
Ions are taken into the body by what? And absorbed into the what?
Food
Blood
What is wrong with having the wrong ion or water content?
Too much or too little water is drawn into cells by osmosis. Having the wrong water content in cells can damage them and mean they don’t work as well as normal
What removes excess ions?
The kidneys
Where are ions also lost through (apart from kidneys)?
