Detailed explanation-1: -Temperature: Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working. pH: Each enzyme has an optimum pH range.
Detailed explanation-2: -Enzymes are also subject to cold denaturation, leading to the loss of enzyme activity at low temperatures [11].
Detailed explanation-3: -Temperature. At low temperatures, the number of successful collisions between the enzyme and substrate is reduced because their molecular movement decreases. The reaction is slow.
Detailed explanation-4: -Higher temperature generally causes more collisions among the molecules and therefore increases the rate of a reaction. More collisions increase the likelihood that substrate will collide with the active site of the enzyme, thus increasing the rate of an enzyme-catalyzed reaction.
Detailed explanation-5: -The working of enzymes is slowed down with the lowering of temperature, while higher temperatures destroy them. This flexibility is essential to how enzymes bind to other molecules and cause chemical reactions to happen on those molecules.
