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.

What type of molecule would be most affected by a dangerous increase in the organism's body temperature?

nobody knows


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.


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.


Would a higher enzymes concentration make the reaction faster or slower?

Increased enzymes would increase the rate of the reaction up to a certain point. They would reach a point where there are no more reactions to help out.

How would adding baking soda to the contents of the stomach affect the activity of the enzymes?

Adding baking soda to the contents of the stomach would increase the pH, making it more basic. This change in pH would likely affect the activity of stomach enzymes, which function optimally at an acidic pH. Consequently, the enzymes may not work as effectively, potentially leading to decreased digestion of food.

There would be an increase


How would you adjust the temperature to increase the amount of production?

Increasing the temperature would shift the equilibrium to the right and increase the amount of product.


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.

If temperature increase what happens to pressure?

Are you referring to gases?In gases,if the temperature increases then the pressure would also increase.


If you were able to increase the kinetic energy of the molecules inside your body your body temperature would?

increase as kinetic energy is directly related to temperature. The molecules would move faster, increasing collisions and thermal energy, causing an increase in body temperature.
