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.

Option C) Raw liver produced the most oxygen bubbles, followed by raw potato.

i.e  H₂O₂  →   H₂O ₊ 1/2 O₂

i.e  2 H₂O₂  ₊  catalase  →  2 H₂O  ₊   2 O₂.

Result: Raw liver produces maximum fizz followed by raw potato.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
