    For 6c) in this paper, I put because the most hydrogen and oxygen are produced in the liver, indicated by the greatest height of bubbles. However, the mark scheme mentions nothing about hydrogen and oxygen but aren't water and oxygen formed when hydrogen peroxide is broken down? Thanks.

    Why do you think hydrogen is produced when the question says hydrogen peroxide is broken down into water and oxygen? This is an example of how important it is to read the question properly and understand it before attempting the question.

    Hydrogen peroxide is not broken down into hydrogen.
