Foam formation
The foam produced is a result of catalase converting hydrogen peroxide into
water and oxygen
The bubbles are filled with (). The more bubbles produced, the () catalase is carrying out this thisreaction,or the more catalase is present
oxygen, faster
The more foam produced, the () the catalase enzyme activity.
better
Less foam, less
activity
