The table below shows the results of an experiment done by juan and cindy. juan and cindy placed hydrogen peroxide on several food samples and recorded the relative amount of fizz that each produced. the fizz was produced by oxygen bubbles released by the action of the enzyme catalase, which is found in almost every living cell. which of these is a valid conclusion from their data?

a) plant cells produce more oxygen bubbles than animal cells.

b) boiled potato and cooked liver produced the most oxygen bubbles.

c) raw liver produced the most oxygen bubbles, followed by raw potato.

d) cooking the foods seems to increase the activity of the catalase enzyme.
