Because by macerating it, you increase the surface area. Therefore you will have a faster reaction. More O2 will form in less time.
When Hydrogen Peroxide (2H2O2) is combined with a small piece of liver, the hydrogen peroxide decomposes. This is because the small piece of liver acts as a catalyst, or the cause, of the decomposition of the Hydrogen Peroxide.The balanced equation is thus:2H2O2 (Hydrogen Peroxide) ---------> 2H2O + O2
Boiled liver reacts with hydrogen peroxide because liver contains enzymes called catalase, which catalyze the breakdown of hydrogen peroxide into oxygen gas and water. This reaction produces bubbles of oxygen gas, which is visible as a foamy reaction when hydrogen peroxide is added to boiled liver.
Mixing hydrogen peroxide and liver could potentially cause a chemical reaction that releases oxygen gas, bubbles, and heat. This reaction could be dangerous due to the release of oxygen gas, so it is not recommended to carry out this experiment.
The enzyme in the liver (catalase) decomposes the hydrogen peroxide (H2O2) into water and oxygen molecules. However this reaction will be slower then the liver being at 37 degrees celsius as this is the optimal condition for the enzyme catalase. The reaction will occur at a slower rate when an enzyme is below its optimal condition so generally when an enzyme is in cold conditions it will function slower.
Enzymes are found in the liver and as you know enzymes are hightly specific biological catalysts. One of the enzymes that is found in liver is the enzyme called a peroxidase enzyme, whose job it is to break down any hydrogen peroxide that exists in the body. It is important to note the dependance on concentration of the enzyme, the PH of the system(as enzymes only like to work ay body ph). The peroxidase enzymes generally break up molecules in the form ROOR into ROH and R'OH where the chain length of R varies.
By macerating the liver, you are increasing its surface area (SA) therefore, the enzyme catalase can break down the hydrogen peroxide at a much faster and easier rate.
The peroxidatic function of the liver is the function that creates hydrogen peroxide.
When liver and hydrogen peroxide mix, they produce a liquid called hydrogen peroxide. The liver contains an enzyme called catalase, which breaks down hydrogen peroxide into water and oxygen gas.
Hydrogen peroxide is an oxidising agent, and oxidation is an exothermic reaction. The liver is being oxidised.

The liver breaks down hydrogen peroxide consistently throughout the year, regardless of the season. The enzyme catalase in the liver helps convert hydrogen peroxide into water and oxygen, a process that occurs continuously to prevent the accumulation of harmful hydrogen peroxide in the body.
You can decompose hydrogen peroxide into water by adding a few pieces of uncooked diced potato or liver to it. Both potatoes and liver contain enzymes that will break down hydrogen peroxide.

Peroxisomes are the enzyme-filled sacs found in the liver that produce hydrogen peroxide as a byproduct of their metabolic functions. Hydrogen peroxide is then broken down by the peroxisome's enzymes to prevent cellular damage.
Beef liver fizzes when treated with hydrogen peroxide due to the presence of the enzyme catalase, which is abundant in liver tissue. Catalase catalyzes the breakdown of hydrogen peroxide into water and oxygen gas. The release of oxygen creates bubbles, resulting in the fizzing reaction. This is a demonstration of the enzyme's activity and its role in detoxifying hydrogen peroxide in living organisms.
