what happend to enzyme after reaction?

[Dencology]

would you help me with this questions:

what happens to an enzyme after a reaction takes place?

a. the enzyme is degraded and recycled
b. it participates in negative feedback
c. it realeases substrate and further catalyzes
d. it is inhibited by product
e. it is permanently confromed into the tense state

i chose A. but the ans. is C. any suggestion?

Enzymes aren't degraded after reactions, they release the substrate (really the product) and look for another substrate.

Enzymes come out of the reaction unchanged.

i don't have a date yet but i am thinking to take it in three weeks. why?

 

[bustedgrill]

Enzymes are never degraded. The can be inhibited or regulated though. I would have went with C as well.

This is a really basic biology question... have you taken biochemistry???

Yea man, this question is really not hard, if your not sure you can use process of elimation. Neurotransmitters are recycled, but proteins which are biocatalysts are never used up in reaction or "recycled". Read Cliffs AP Bio, just memorize and google search. I think I posted 1 or 2 questions when I absolutely could not find anything about them.

lol i think you're thinking of what happens in the synaptic cleft.

but speaking in a chemical sense, enzymes are part of a reaction but they are always returned as they were in the beginning of the reaction after the reaction is over

not a big deal.

you prob just made that assumption

All but b and e could happen IMO.

A: cell doesn't need it anymore...degraded.
B: don't think this could happen
C: Most basic concept of an enzyme
D: Phosphofructokinase does this I think. Makes a lot of sense (basic concept of neg inhibition)
E: If the substrate is a toxin that causes irreversible inhibition. Sort of depends on wording technicalities, could see it go both ways.

i was thinking the same. but i think b and e can happen also.

but the thing is since this question is so general the most general answer is correct and not any of the specific ones
