Question

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.

Answer 1

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

Step-by-step explanation:

• The Hydrogen peroxide is highly unstable compound and gets converted to water and half oxygen.

i.e H₂O₂ → H₂O ₊ 1/2 O₂

• This Half Oxygen molecule produces fizz in the food.
• The enzyme catalase increases the rate of reaction.

i.e 2 H₂O₂ ₊ catalase → 2 H₂O ₊ 2 O₂.

• According to the given data Raw liver produces maximum fizz followed by Raw potato followed by cooked liver then boiled potato.

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