A keyboard is also used to give commands to the operating system of a computer, such as Windows ' Control-Alt-Delete combination, which brings up a task window or shuts down the machine. A command-line interface is a type of user interface operated entirely through a keyboard, or another device doing the job of one.
How Temperature Affects Enzymes. Higher temperatures tend to speed up the effect of enzyme activity, while lower temperatures decrease the rate of an enzyme reaction. At higher temperatures, more molecules collide, increasing the chance that an enzyme will collide with its substrate.
As the saturation of hydrogen peroxide increased the rate of reaction increased as well. When the enzyme concentration increased the rate of catalase activity increased too. When catalase was subjected to an increase of temperature changes, the rate of reaction increased.hen the enzyme concentration increased the rate of catalase activity increased too. When catalase was subjected to an increase of temperature changes, the rate of reaction increased.
