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.
The flexibility of. that enzyme could be affected due to the effect of temperature on covalent and hydrogen bonds. Chemical bonds make up the shape of protein and proteinâs function is related to its shape and. therefore activity would decrease or impact the enzyme catalyzing a reaction (Reece, et al 2010).
