Enzymes are proteins. Protein function is related to the 3-D structure of the protein, which may be affected by pH. Proteins are also buffers that maintain pH within a certain range, but when the limits of this range are exceeded, the protein is denatured and cannot function.
High temperatures can denature enzymes, altering their shape and making them less effective. Low temperatures can decrease enzyme activity by slowing down the rate of reactions. Both extremes can ultimately inhibit enzyme function and impact biochemical processes in the body.
Like anything else, enzymes operate best under optimal environmental conditions. Two major influencing factors are temperature and pH. At excessively high temperatures the enzyme may be less efficient and outside the optimal pH range enzyme activity will slow.
Changing the temperature of an enzyme will denature it, meaning it will basically "turn it off," causing it to not work properly anymore.

What conditions affects the function of enzymes?
Conditions such as temperature, pH, substrate concentration, and enzyme concentration can affect the function of enzymes. High temperatures can denature enzymes, extremes in pH can alter their structure, low substrate concentration can slow down reaction rates, and low enzyme concentration can limit the rate of reaction.
Can temperature affect enzymes?
Yes, temperature can affect enzymes. Enzymes have an optimal temperature at which they work best, typically around body temperature for human enzymes. Higher temperatures can denature the enzyme, affecting its shape and thus its function. Cooler temperatures can slow down enzyme activity.
How does temperature change the action of enzymes?
Temperature can affect enzyme activity because enzymes work best within specific temperature ranges. At low temperatures, enzyme activity decreases as the molecules move more slowly, decreasing the likelihood of enzyme-substrate collisions. At high temperatures, enzyme activity can be disrupted because the enzyme structure can become denatured, leading to a loss of function. Optimal temperature for enzyme activity varies depending on the specific enzyme.
At what temperature do plant enzymes work best?
Enzymes work best at temperatures around body temperature. If the temperature is too low, there is too little kinetic energy available for it, but if it is too high, the enzyme will be denatured, and will therefore also work slower. Enzymes work best at temperatures around body temperature. If the temperature is too low, there is too little kinetic energy available for it, but if it is too high, the enzyme will be denatured, and will therefore also work slower.
How are enzymes damaged by high temperature?
High temperatures can denature enzymes by breaking the bonds that maintain their specific three-dimensional shape. This altered shape can disrupt the enzyme's active site, preventing it from interacting with its substrate efficiently, and therefore, leading to a loss of enzyme activity.

Why humans have a defined body temperature?
So the enzymes function properly, temperature too low = inefficient working due to not enough kinetic energy, temperature too high means the enzymes will denature (die!)
How does low and high temperature affect the activity of enzyme?
The higher the tempreature, the higher the rate of reaction, however 37 degrees (body temperature), celcius is the optinum temperature, then after this point the enzymes will start to denature. this is due to the fact that the particles gain kenetic energy and subsequently move around more vigirously. Thus, the chance of there been a successful collision between the enzyme and substrate molecule increases as reacting particles will collide more frequently with increased kinetic energy.
Describe and explain how pH and temperature affect enzyme activity?
Enzymes are temperature bound too high temperature denatures their cells while too low temperatures renders them inactive. The same mechanism applies to pH there are those enzymes that thrive well in acidic conditions while there are those that thrive in basic condition and therefore if the conditions are reversed the enzymes' cells are denatured.

When do chemical reactions involving enzymes slow down?
Chemical reactions involving enzymes slow down when the temperature is too high or too low, as enzymes have an optimal temperature range for activity. Additionally, changes in pH levels can also affect enzyme activity, causing reactions to slow down. Lastly, the presence of inhibitors or competitive molecules can hinder enzyme function, leading to a slowdown in reactions.
Why do washing powders have enzymes with a low temperature?
Enzymes in washing powders that work at low temperatures help to break down stains and dirt effectively without requiring high heat. This is beneficial for energy efficiency and can prevent damage to delicate fabrics that may not be able to withstand high temperature washing. Additionally, using enzymes at lower temperatures can help reduce shrinking and fading of colored clothing.
