cold temperatures cause enzymes to inactivate, meaning they are no longer useful. at height temperatures enzymes denature, meaning they are also no longer useful. The difference is that at low temperature, when an enzyme inactivates it can always be heated, and used again. Yet after an enzyme is denatured by heat it is destroyed, this is because the heat causes the enzymes to lose its shape, making it imposible for the substrate to react with the enzyme.

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.
Why does your body allows chemical reactions to occur at low temperature?
The body allows chemical reactions to occur at low temperatures to maintain proper functioning of enzymes and cellular metabolism. Enzymes have evolved to work optimally within the range of temperatures found in the human body, allowing metabolic reactions to proceed efficiently and effectively to support life processes. Additionally, low temperatures help to prevent denaturation of proteins and preserve the structural integrity of biological molecules.
How does substrate concentration and pH affect enzymes?
Substrate concentration will affect enzymes because substrates are specific to enzymes. The pH will affect enzymes because certain enzymes will work better in certain pH levels.
How do Enzymes permit low temperature reactions?
Enzymes permit low-temperature reactions by stabilizing the transition state of a reaction, reducing the activation energy required for the reaction to occur. This allows the reactions to proceed more readily at lower temperatures. Enzymes achieve this through their specific three-dimensional structures that provide an optimal environment for the reaction to take place.
What are ''thermolabile enzymes''?
Thermolabile enzymes are enzymes that are sensitive to heat and can be denatured or destroyed at high temperatures. These enzymes have optimal activity at lower temperatures and are typically found in organisms living in moderate environments. Heating can disrupt the structure of thermolabile enzymes, rendering them nonfunctional.
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.
What is the advantage of washing clothes at such low temperatures?
Washing clothes at low temperatures, such as 30°C or below, helps to save energy and reduce your electricity bill. It can also extend the lifespan of your clothes by preventing shrinkage and color fading that can occur with higher temperatures. Additionally, washing at lower temperatures is more environmentally friendly as it reduces carbon emissions associated with heating water.
Does heat affect the efficiency of catalase?
Yes, heat can affect the efficiency of catalase. At low temperatures, catalase activity may be slower due to slower enzyme-substrate collisions. At high temperatures, the enzyme may denature, leading to a loss of catalytic activity. The optimum temperature for most catalase enzymes is around 37°C.
Can temperature affect enzymes?
Yes, temperature does affect the activity of enzymes. If the temperature increases too much, the enzyme can denature (unfold) itself which will move key amino acids necessary for enzymatic function away from each other, preventing enzymatic activity.
Why do laundry enzymes clean stains better at low temperatures?
Laundry enzymes work better at low temperatures because they are less likely to denature or break down when not exposed to high heat. This allows them to maintain their effectiveness in breaking down and removing stains from clothes even in cold water washing.
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.
Are Enzymes are able to work at any temperature?
Enzymes have an optimal temperature at which they work best, usually around body temperature for human enzymes. Extreme temperatures can denature the enzyme, causing it to lose its shape and function. Some enzymes from extremophiles are adapted to work at very high or low temperatures.
Why do washing powders have enzymes with a low temperature?

Additionally, using enzymes at lower temperatures can help reduce shrinking and fading of colored clothing.
What effect does low temperature have on photosynthesis?
Low temperatures can slow down the rate of photosynthesis because the enzymes involved in the process become less active. This can lead to reduced carbon dioxide fixation and ultimately lower production of glucose and oxygen. Extremely low temperatures can even damage the plant cells and photosynthetic machinery, affecting overall growth and survival.
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.
