In general, increased temperature will increase the activity of an enzyme. However, this is a general trend. For one thing, eventually, if you increase temperature enough you will reach a point at which the protein which makes up the enzyme will begin to denature (unfold). When this happens, the enzyme can no longer be active. Almost all enzymes have an "optimal" temperature. For example, most human derived enzymes will function best at around 37C (body temperature) but this is not always true. Temperature can have other effects as well. Enzymes perform their work on what is called a substrate. The substrate may also be affected by temperature. For example, there is an enzyme commonly used in molecular Biology called ligase. Ligase joins to pieces of DNA together. Obviously the natural temperature for ligase to operate in humans is 37C, but in the lab, when we use ligase we often perform the reaction at a much lower temperature (14-16C). The reason for this is that at higher temperatures, the double stranded DNA starts to melt (separate into single strands) which makes it more difficult for ligase to work. At lower temperatures, the DNA stays double stranded making it easier for ligase to work.

∙ 12y agoInitially, an increase in temperature will increase the rate of reaction - and the enzyme should be able to catalyse the reaction faster. However, past a certain point, which is different for different enzymes, the shape of the enzyme will change. This is known as denaturing, and means the enzyme will not be able to catalyse the reaction efficiently (or at all).

∙ 14y agoUsually when there is a temperature increase enzymes become more active because you are adding energy to a system. If the temperature rises too high, however, these enzymes will denature.

∙ 11y agoAny significant change in conditions (including temperature) can cause a protein (enzymes are a type of protein) to denature, or fold differently so it won't do its specific job anymore.

What type of molecule would be most affected by a dangerous increase in the organism's body temperature?
nobody knows
How does the addition of heat to a liquid affect its average kinetic energy?
It would increase its average kinetic energy which would be apparent by an increase in temperature.
What affect does urbanization has on temperature?
The primary affect urbanization has on temperature is to increase it overall. Because of the concentration of people, buildings, and equipment, nature is unable to dissipate all the heat as it normally would.
How does temperature affect fermentation?
Yeast fermentation is affected by temperature as a result of the various different standards of temperatures that the yeasts are exposed to. If the yeasts are exposed to their optimum temperature(approximately 66.667 degrees Celsius), then this would yield the most amount of fermentation. However, the process by which fermentation occurs in the first place is by respiration, which obviously includes enzymes. Thus, if yeast cells become denatured, as a result of a too high temperature, which causes the yeast cells enzymes to be denatured, then the yeast would not ferment to the best of their ability, hence causing a decrease in the rate of fermentation. Likewise, if the yeast cells are exposed to low temperatures, then the yeast cells would be inhibited, and so they would also not work. However, this can be fixed unlike the prior case. When temperatures become optimum again, the yeast would ferment as usual again.
How would an increase in mass affect the basic properties of a star?
As mass increases It increases the surface temperature , luminosity, and radius.

How do enzymes affect the chemical reactions occurring in cells?
Enzymes are catalysts. They help lower the activation energy of reactions and increase the rate of the reaction. Without the help of enzymes, the biochemical reactions in the body would take so long that it would kill the person.
Would a change in the temperature of the core affect plate tectonics?
A change in temperature of the core would probably have to be rather large to be noticeable, however it would affect plate tectonics. Lowering the temperature of the core would slow down activity and raising it would increase.

How do emotional state affect the body temperature?
With emotional states, the body would either increase metabolism for energy or decrease metabolism.
How does the high concentration of carbon dioxide in the atmosphere affect Our environment?
For one, it contributes to Ocean acidification.
What would INCREASE the rate of dissolution but not affect the solubility of salt in water stirring or heating it?
Stirring and heating improve the rate of dissolution and not affect the measured solubility at a given temperature.But I mention that the solubilty of solids is increased when the temperature increase.
What connection can be made between enzyme activity and temperature?
Temperature can directly affect enzyme activity. Increases in temperature can cause the enzymes to operate at a quicker pace and cause the enzymatic reaction to move along faster, while decreases in temperatures can cause the enzymes to become sluggish and the reaction to slow down. If temperatures are too high, then the enzymes can fall apart, or denature due to the extreme heat, and if temperatures are too low, then the enzymes can slow down to a complete halt in some cases. Either way, the enzymatic reaction will stop. Most enzymes have an optimal temperature under which they can work the most efficiently and effectively.
Would there be an increase or a decrease in the rate of osmosis if WE raised the temperature?
There would be an increase
