Enzymes Temperature Coursework

Enzymes Temperature Coursework-4
Catalase can help break down other harmful chemicals in the body such as alcohol, phenol, and formaldehyde (Vitamin Stuff.com).As mentioned before, enzymes play a significant role in organic chemistry.

Catalase breaks down hydrogen peroxide, a very harmful oxidizing agent for cells (Catalase).

A single catalase molecule can break down millions of hydrogen peroxide molecules in a given moment.

Like most chemical reactions, the rate of an enzyme-catalyzed reaction increases as the temperature is raised.

A ten degree Centigrade rise in temperature will increase the activity of most enzymes by 50 to 100%.

Variations in reaction temperature as small as 1 or 2 degrees may introduce changes of 10 to 20% in the results.

In the case of enzymatic reactions, this is complicated by the fact that many enzymes are adversely affected by high temperatures.

As shown in Figure 13, the reaction rate increases with temperature to a maximum level, then abruptly declines with further increase of temperature.

Because most animal enzymes rapidly become denatured at temperatures above 40°C, most enzyme determinations are carried out somewhat below that temperature.

Factors include: concentration of the enzyme, temperature, p H level, concentration of the substrate, and inhibitors.

This lab shows the affects these factors have on the rate of reaction between catalase, an enzyme found in potatoes, and hydrogen peroxide, the substrate.
