Some incorrect answers, but overall, a good quiz.

A useful set of questions on homeostasis. The answer to question 16 is a bit debatable as not all amino acids can be converted into the same things. For example some can be converted into glucose (by a number of steps) after removal of the amino part and some can't. Some can be converted into a compound that can be turn into lipid and others can't. Hope this helps.
