Competitive inhibition and feedback inhibition?

Question

Can you PLEASE write five different statements comparing and contrasting them?

I would SO be in your debt. You'd be a lifesaver. 10 points no matter what if you answer this! Thanks!

Answer 1

Read your book, do your own homework.

If you aren't going to even try to do it, then why should I try to help?

(addition) well, then you should have paid attention in class, give me something to show that you know anything about it and I'll be more than happy to help.

Answer 2

1). In competitive inhibition due to structural similarity between substrate and inhibitor some times inhibitor will bind to the active site of enzyme and inhibit the reaction.

2)Concentration gradient is the characteristic feature of competitive inhibition.if inhibitor concentration is more, then inhibitor suppress the substrate and bind to active site and inhibit the reaction.vise versa take place if substrate concentration is more than inhibitor.competition take place between inhibitor and substrate for active site that's why this type of inhibition is called competitive inhibition.

Feed back Inhibition:This inhibition mainly depends on product concentration, if product concentration is less, then only reactents converted to products. if product concentration is high reaction will  be inhibited by inhibiting specific enzyme involved in that reaction.

2).This type of inhibition mainly take place in Allosteric Enzymes.Due to high product concentration product will bind to allosteric site and inhibit the reaction.

3).cell unnessarily  does not waste energy,If product concentration is less then only reaction proceed forward.

Answer 3

1. Competitive inhibitors typically compete with the substrate for binding the active site, while non-competitive inhibitors (which display feedback inhibition) bind to the allosteric sites of the enzymes.

2.  Competitive inhibitors increase the Km of enzyme (decreasing affinity for substrate), while non-competitive inhibitors decrease the Vmax of the enzyme (decreasing its maximum speed)

3.  Competitive inhibitors can be overcome by increasing substrate concentration, whereas non-competitive inhibitors cannot.

4.  Both types of inhibition slow enzyme act

ivity.

5.  There can be allosteric (non-competitive) activators that increase enzyme activity, but its unlikely that you will find any competitive activators.
