how does cold temperature affects enzyme activity? Explain

[canalon]

Why don't you want to read your textbook? Explain.

[MrMistery]

Hint: when you post homework questions, don't say explain at the end, cause we will recognise the question as part of your homework and deffinetly won't do it for you.

[Darby]

We'd probably give you the "wrong" answer, anyway - most introductory texts give an explanation that is so simplified that it's hardly an explanation at all.

[canalon]

Enzymes start shivering because of the cold, and their little hands are more prone to do their job correctly, so they need to work slower to keep their efficiency. But sometimes, just like bears they fall asleep if the temperature is too low burrying themselves in a ribosome cave with plenty of substrate stored in prevision of the rise of the temperature...

No seriously, look at the thermodynamics of chemical reaction. It applies to enzymes too.

[mith]

Well...at least it's moderately better than copy and paste....

[vergil5203]

well,firstly i think is enzyme hard to catalysis when a cold temperature it because the substance hard to find to enzyme active side..isn't it?

[biostudent2]

Actually I was wonder about that too. Does less enzyme activity have anything to to do with the freezing of bonds? Also, could it be any bonds that are trying to connect to the enzyme, such as the freezing of hydro bonds in water? It seems like enzymes in cold temp would be preserved not destroyed.

Thanks-

you should understand what freezing means, an atom cannot freeze really, ice is just water arranged into a crystal lattice.

Haha, I find this amusing.

ill tell you this when you heat it after a certain heat it starts to react less well thats above 50 * not sure how high but imagine 0 being the just working point so what happens if its below the zero point? its gonna work? or no? why and how it dosnet work u figure out.

ps after 0 it the enzmye s activity begins to increases.

[smrtrthanauniversitygrad]

A decrease in temperature causes the rate of enzyme activity to slow down. b/c the molecular motion decreases.
