Question

At your lab station, you put 30 mL of hydrogen peroxide into three separate beakers and add 2 grams of ground up liver to each one. You place one beaker in a warm water bath and one beaker in an ice water bath. One beaker is kept at room temperature. Large numbers of bubbles are observed forming in the beaker with the warm water, a moderate number in the room temperature beaker, but almost no bubbles are produced in the cold version of the experiment.Based on the investigation above, what inference can be made about the results?

Answer 1

Based on the investigation, the inference that can be made about the result is that catalase activity increases with warm temperature.

The liver usually contains an enzyme known as catalase that is capable of breaking down hydrogen peroxide into water and oxygen gas. The bubbles observed in the beaker during the investigation represent the oxygen being evolved from the breakdown of the hydrogen peroxide by the catalase in the liver sample.

At room temperature, a moderate number of oxygen bubbles were observed.  The number of bubbles increased with increased temperature as a result of placing the beaker in a warm water bath. At a lower temperature brought by placing the beaker in an ice water bath, no bubbles were observed.

Thus, we can effectively conclude that the activities of the catalase enzyme in the liver increased with a moderately increased temperature.
