he cold is not as intuitive as heat. Heat is the abundance in a system and cold is the absence of energy in a system. Hence athermometer is the an instrument that measures the average kinetic energy of its surroundings. Why do enzymes not work as well in the cold it is because the energy of the system is decreasing causing the molecules to "slow down" there by slowing the diffusion in a system. The enzymes normal substrate is not diffusing a quickly as it would in a heated system, raising the enzymes Km ( affinity for its substrate ).

∙ 11y agoEnzymes are often inactive at low temperatures due to the fact that there is not much energy to allow the enzymes to move around so that the substrate/enzyme can bind.

Why don't detergents work well at higher temperatures?
Because enzymes denature/change shape at high temperatures and detergents contain enzymes.
Enzymes tend to raise the activation energy?
Enzymes lower the amount of activation energy required. This makes the reaction more likely to occur and speeds it up as well.
Why dont enzymes digest the cell itself?
The reason why a lysosome does not digest itself or the cell is because it has an inner membrane that is coated with glycocalyx. This membrane contains poly-lactosamine which prevents the digestive enzymes from gaining access.
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.

Because enzymes denature/change shape at high temperatures and detergents contain enzymes.
Does all enzymes work well on every temperature?
Far from it. Most enzymes only work well in a characteristic, rather narrow range of temperatures.
Enzymes tend to raise the activation energy?
Enzymes lower the amount of activation energy required. This makes the reaction more likely to occur and speeds it up as well.
Why would different enzymes have different temperature ranges with different optimal temperatures?
Well, it depends on where in the body the enzyme is located. however, all enzymes in the human body work within a very narrow temperature scale, they don't all have the exact same optimal temp, but they are close. for instance, enzymes in the scrotum have to be able to work at a temp three degrees or so lower than the average human body temperature.
Is Wood a good heat insulator?
noansw2. Well, for lower temperatures, well removed from the ignition point of wood, it is quite a suitable thermal insulator.
How do you keep an electric frying pan or griddle from burning and smoking?
Clean well and cook at lower temperatures when using grease or butter.
Why dont enzymes digest the cell itself?
The reason why a lysosome does not digest itself or the cell is because it has an inner membrane that is coated with glycocalyx. This membrane contains poly-lactosamine which prevents the digestive enzymes from gaining access.
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.
When can refrigeration not applicable to preserve sample for enzymatic assay?
Refrigeration is not applicable to preserve sample for enzymatic assay because enzymes may lose their activity at extremely low temperatures as well. This may account for storing enzymes at 5° C or below without affecting the enzymatic activity permanently. (Anubhav, 2012)
