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.
Best Answer: An increase in temperature results in more kinetic energy of the enzyme and the substrate. More kinetic energy results in more collisions between the enzyme and the substrate. In turn, the number of successful collisions increases and more enzyme-substrate complexes form.Therefore an increase in temperature increases the rate at which enzyme substrate complexes form. However, all enzymes have an optimum temperature at which it will work best and favour the activity.Eg. pepsin, an enzyme which works in the stomach has an optimum temperature of between 30-40oC, which is around the human body temperature.owever, all enzymes have an optimum temperature at which it will work best and favour the activity.
