Which enzyme has the highest temperature in which it can work the fastest?
Q. I need the name of the enzyme and it's temperature where it is working the fastest? Research for a film. Yeah, I mean ones that aren't in humans, my films are set in a time when humans have colonised space and they end up encountering an incredibly hard to kill and incredibly hostile race which evolved in some pretty harsh conditions.
Asked by Lily R - Wed Jan 13 15:28:30 2010 - - 1 Answers - 0 Comments

A. well in humans the highest temperature is 37 degrees celcius and generally the optimum temp for enzyme action but there are enzymes in bacteria that live in hot springs that can work at normally denaturing temperatures like 100 degrees. an example would be thermostable DNA polymerase (used in pcr)

A. pepsin degrades proteins into amino acids and not build them the enzyme that buils is part of ribosome and it builds from the n-terminal to c-terminal

A. Term "Enzyme" means protein in nature. Enzymes are biological protein catalysts in the living cells. Enzymes are involved in all biological processes and metabolism . They facilitate the conversion of substrate molecules to product but are not themselves altered by the reaction. Enzyme-catalyzed reactions differ from ordinary chemical reactions: 1- High specificity: they are capable of recognizing highly specific differences in substrate and product molecules. 2- High reaction rates: the rate of enzyme catalyzed reactions are million times to million million times greater than that of uncatalyzed reactions. Many enzymes are capable of converting thousands of substrate molecules every second.

If an enzyme catalyzes two different chemical reactions, than which of the following is correct?
Q. A. The enzyme contains both -helices and -pleated sheets. B. The enzyme is subject to both competitive inhibition and allosteric regulation. C. Two types of allosteric regulation occur: The binding of one molecule activates the enzyme, while the binding of a different molecule inhibits it. D. Either the enzyme has two distinct active sites, or the reactants involved in the two reactions are very similar in size and shape.

How does an enzyme and a substrate combine?
Q. A specific substrate will have a complementary binding site. When it binds with an enzyme, the formation 'changes', and as a result the bond breaks,leaving the substrate as separate product molecules. What brings on the 'change' when the substrate and the enzyme combine?
Asked by alexa.deimos - Thu Oct 9 06:53:26 2008 - - 3 Answers - 0 Comments

A. Binding site or active site of an enzyme has reactive groups that aid in chemical reaction. e.g. H2O might be added across the bond and hydrolysis will take place. Similar manner other groups bring about other changes and substrate is converted to a product.

What happens to catalayse activity if the enzyme's temperature is lowered?
Q. I know that enzyme's are no longer usuable after the temperature/Ph is raised. But what if the temperature is lowered?
Asked by Butt - Sun Mar 15 16:17:28 2009 - - 3 Answers - 0 Comments

A. Generally, as temperature is decreased, the rate of activity of an enzyme also decreases. This is because temperature is actually a measure of molecular motion. As the molecules move more slowly, they are less likely to bump into each other, so the enzyme is less likely to meet the substrate. If they don't meet, the enzyme can't break down the substrate...

A. You mean when they eat gluten (like wheat, barley, etc)? People with Celiac Disease get pain in their intestines when they eat certain fibers that have gluten in them... I've never heard of other diseases like that. If that's the case, there is only one product I've heard of that helps to digest gluten, and that's called "BioCore DPP, Gluten Peptide Enzyme"... you should be able to find it online or in your local health food store. If you mean they just get cramping, that's very common if they don't eat much fiber at all. If that's the case, the others are right that no enzymes will break down fiber in general... your friend just needs to slowly bring up their fiber intake.

Asked by Casy F - Tue Sep 9 02:34:28 2008 - - 2 Answers - 0 Comments

A. As well as urea - excess salts can mask charged side-chains on proteins and cause the protein to denature. For proteins with disulphide bridges, then reducing conditions can convert the -S-S- back to a -S-H H-S- Guanidium hydrochloride also does the same thing as urea.

A. That's ridiculous, actually. There are animo acids that are found in larger quantities in meat than vegetarian sources (I believe that's what they meant, based on your use of "enzyme" and "protein"), but you can get all of the essential amino acids from plant-based foods. Some people are convinced that you can't, or that you have to carefully combine them at each meal, but science is on our side. Tryptophan, which your brain uses to process seretonin and other nice happy-feeling neurotransmitters, is actually more plentiful (by weight) in some vegetarian foods than it is in meat foods. Just look up amino acids and their functions to see what does what. Then look up dietary sources and you'll see that you can easily get them without… [cont.]
