When enzymes are heated to high temperatures they can denature which means that they sort of fall apart as the bonds which hold the amino acids (the molecule that makes up an enzyme) together. when the enzyme denatures it looses its shape and cannot bind with the substrate (the thing it is trying to break down).
Almost all enzymes are biochemically active at metabolic temperatures, i.e., mid 30's to 38 degrees Celcius. Moreover, the temperature affects directly to the tertiary and secondary structures disrupting hydrogen bonds, van der Walls and ionic forces

∙ 14y agoAt a high temperature the rate of reaction of the enzymes starts to decrease, this is because when the temperature starts to significantly increase, weaker forces that maintain the shape of the molecule are disrupted instead of kinetic energy being created. Which results in the active site of the enzymes to change. Enzymes are specific, so once the active site has been change, then the enzyme will cease to function.

∙ 15y agoHigh temperature increases the kinetic energy of molecules and can cause the delicate and precariously maintained three-dimensional structure of proteins to be disrupted (the process is called denaturation). Most enzymes require a very specific three-dimensional conformation to perform their functions and therefore a disruption in their folding can greatly impair their function.

How are enzymes degraded?
Enzymes can be denatured if the pH is too acidic or basic, or at very high or low temperatures.
Why are high temperatures not suitable for anaerobic fermentation?
Temperatures in excess of 40oC will denature the enzymes (proteins) in the yeast, which makes them inactive.
Why do enzymes stop working at high temperatures in the process of photosynthesis?
Enzymes stop working at high teperatures during photosynthesis because the heat changes their shape. If the enzymes shape is altered then it can not catalize what it is supposed to.
Why don't detergents work well at higher temperatures?
Because enzymes denature/change shape at high temperatures and detergents contain enzymes.
How are enzymes damaged by high temperature?
The body has its own normal temp. And enzymes function along with body temp, you go to high or low it can cause severe damage to the body. Enzymes are proteins, and they are denatured (change in structure) when expose to high temps.
9 What happens to enzymes if you heat them up?
enzymes undergo denaturation when heated to high temperatures
How are enzymes degraded?
Enzymes can be denatured if the pH is too acidic or basic, or at very high or low temperatures.
Enzymes can denature by?
High temperatures, acidity or basicity, radiation, etc.
Why are high temperatures not suitable for anaerobic fermentation?
Temperatures in excess of 40oC will denature the enzymes (proteins) in the yeast, which makes them inactive.
Enzymes have optimal temperatures.most human enzymes have an optimal temperature of about?
The optimal temperature of enzymes in humans is about 37c, the same as the human body's temperature. However, some enzymes work at higher temperatures than 37 but not very high because higher temperatures denatures (destroy) the enzymes.
Why do enzymes stop working at high temperatures in the process of photosynthesis?
Enzymes stop working at high teperatures during photosynthesis because the heat changes their shape. If the enzymes shape is altered then it can not catalize what it is supposed to.
Why are some bacteria metabolically active in hot springs?
Their enzymes have high optimal temperatures.
Very high body temperatures are often fatal because they can?
inactivate critical enzymes
Why don't detergents work well at higher temperatures?
Because enzymes denature/change shape at high temperatures and detergents contain enzymes.
Some bacteria are metabolically active in hot springs because?
their enzymes have high optimal temperatures.
A permanent change in the shape of the enzymes active site caused by high temperatures?
A permanent change in the shape of an enzyme's active site caused by high temperatures is called denaturation.
Is the enzymes affected temporarily or permanents?
That depends on the physical conditions. High temperatures, some substances or changes in pH cause enzymes to be permanently denatured. Very low temperatures and the presence of some inhibitors cause enzymes to be temporarily unable to catalyse reactions.
