How does a decrease in temperature affect the rate of enzyme reaction?

The higher a temperature is, the faster things go. This is because molecules move faster at higher temperatures. The opposite is true for cold temperatures- molecules move slower, and so do the reactions. Temperature also has different effects on specific organisms-- for example, a hot spring bacterium has enzymes that generally work better in hotter temperatures.

∙ 13y agoSome enzymes are more sensitive to changes in temperature than others, but with most enzymes lowering the temperature (from the optimum) would decrease the rate of activity. At some point the temperature would become too low for the enzyme to work properly.

∙ 13y agoAn increase in temperature will result in a faster rate of reaction. To put it simply, higher temperature means there is more kinetic energy within the particles. Due to this, they will move faster, bump into each other more often, and collide more forcefully. All those factors combine to ensure that the molecules align correctly and with enough force that a reaction occurs. The rate of reaction increases with temperature until the temperature rises too high then the enzyme denatures, making them unable to catalyze reactions, and the rate of reaction drops to zero.

∙ 13y agoChanging temperature can speed up or slow down enzyme activity. Depends on the enzyme.

Changes in pH or temperature decrease enzyme activity because bonds break and the enzyme returns to its tertiary structure?
Changes in pH or temperature decrease enzyme activity because bonds b reak and the enzyme returns to it's PRIMARY structure. (not tertiary)
What three factors affect the rate of a biochemical reaction?
1. pH 2. Concentration - Enzyme and Substrate Concentrations (but to a certain degree) 3. Temperature
Why would a washing powder of high pH or low pH be difficult to handle?
actors such as temperature and pH can affect an enzyme's rate of reaction because enzymes are sensitive to pH and heat. Most enzymes can only function in a particular temperature or pH range, and as the enzyme works out of its normal temperature and pH range, it will denature (change in shape so that the active site no longer fits with the substrate and the enzyme can't function).
What are two factors that affect an enzyme function?
Temperature, pH, solute concentration, and salt content just to name a few. Temperature and Ph affect the function of enzymes because our body has a temperature of around 37 degrees and the conditions in our stomach are acidic. So9f or the enzyme to work properly then the working condidtions have to be at least 37 degrees and they need to acidic otherwise the enzyme won't work properly.
What substance can be used to stop enzyme reaction?
prohibitors are used to enzyme reaction
What are 3 factors that affect the speed of an enzyme catalyzed reaction?
3 factors that affect the speed of an enzyme catalysed reaction are: .Temperature .Enzyme Concentartion .Substrate concentration
As temperature decreases the rate of an enzyme-catalyzed reaction also decreases why?
Just like many other chemical reactions, the rate of an enzyme-catalyzed reaction will decrease with temperature because of the decrease in the number of high energy collisions between particles.
What is the relationship between an enzyme temperature and the chemical reaction in which the enzyme is invoved?
Rate increase with temperature up to 40 celcius.But it decrease to 60 celcius and stops after.
Is there any Procedure in enzyme and factors that affect enzyme activity?
pH, temperature, substrate concentration and enzyme concentration influences the rate of reaction
How does the non-competitive inhibitor decrease the rate of an enzyme reaction?
Noncompetitive inhibitors decrease the rate of an enzyme reaction by bonding to an enzyme somewhere other than the active site, deforming it and permanently disabling the enzyme, so that enzyme can never function again, so the rate of reaction decreases.
How does pH affect enzyme functions?
Enzymes lower the amount of Activation Energy needed for a chemical reaction, therefore speeding up the chemical reaction. For an enzyme to do this it needs to be at the correct pH, salinity, and temperature otherwise the enzyme will not be able to work. When an enzyme is in a pH that is not suitable, the enzyme's shape and structure alter and make it unable to speed up a reaction.
What affect would temperature and pH have on the Catalans enzyme?
Just like always, deviating from the desired normal functioning for the enzyme, whether it be in temperature or pH, would result in the enzyme denaturing and therefore being unable to for enzyme substrate complexes, therefore reducing the overall reaction rate.
Changes in pH or temperature decrease enzyme activity because bonds break and the enzyme returns to its tertiary structure?
Changes in pH or temperature decrease enzyme activity because bonds b reak and the enzyme returns to it's PRIMARY structure. (not tertiary)
What are the different factors that could affect the performance of an enzyme?
Several factors affect the rate at which enzymes work: temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.If the amount of the enzyme is kept constant and the substrate is then gradually increased, the reaction speed will increase.The rate of an enzyme-catalyzed reaction increases as the temperature is raised. But freezing will inactive the enzyme and a very high temperature will destroy the enzyme.Very high or low pH values will result in complete loss of activity for most enzymes.Enzyme inhibitors are substances which alter the action of the enzyme and consequently slow down, or in some cases, stop the reaction.
What factors increase the rates of enzyme-controlled reactions?
** TEMPERATURE ** pH LEVEL ** PARTICLE SIZE ** SUBSTRATE CONCENTRATION
What factors affect enzyme production?
you can say enzyme reaction depends on ph, temp
What things might slow down or speed up and enzyme reaction?
The temperature in addition to the pH sacle of something in particular in the environment would affect the rate of speed of an enzyme and would slow down the reaction if it is too high.
