An increase in temperature beyond the optimum causes the enzyme’s active site to become denatured . This means the active site loses its important shape and can no longer form enzyme-substrate complexes, leading to a decrease in enzyme activity.
Is it better to use bio or non bio washing powder?
Biological washing powder and liquids contain enzymes. These help to break down fat, grease and proteins to get clothes clean. … Non-bio doesn’t contain enzymes so is generally gentler, making it a better choice for sensitive skin.

However, at high temperatures the rate decreases again because the enzyme becomes denatured and can no longer function. … As the temperature increases so does the rate of enzyme activity.
What happens to enzymes at low temperatures?
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. The human body is maintained at 37°C as this is the temperature at which the enzymes in our body work best.
