Early binding versus late binding revolve around a conflict between efficiency and flexibility".Comment.?

If you want someone to do your homework for you, you should at least pay them.

Probably because  cohesion forces (forces that bind molecules of the same type together) are stronger then adhesion forces (forces that bind molecules of the different  types together).

At too low a temp. an enzyme remains inactive.\n\nAt too high a temp. It is killed or ineffective or destroyed.

I think (only think) it's because pyruvate (a product of glycolysis) is able to cross the internal membrane thus allowing ATP production with carbon dioxide as a by-product, whilst glucose is unable to do so.\nI would read my two references to check.\nGood luck.

The proteins shape determines its function.  Most proteins have to bind to something else in order to do its job.  If it's not a specif shape, it can't bind.

He is asking for mechanism....Mechanism is how it works. This is a phase equilibria problem. Please refer to A Level option booklet of phase equilibria.

Collective inertia towards innovation. What is a widely used mistake today is the standard tomorrow. Try to worry more about the quality of the writing than the attention to grammatical "rules."

,Good made me think.  The same, I guess in the end your just exchanging electrons.  However, the impulse in the brain will not fire until a certain discharge potential is met.  Also there are moderators in the synapse gap that can slow down the current exchange.  Serotonin is one.

both are important they works differently

It is not the binding alone that activates a receptor. The binding of a molecule to a receptor causes it to change conformation, and the receptor is only activated if it changes into the appropriate conformation.\n\nAlso, there are non-competitive receptor antagonists, which do not bind to the receptor at all, but usually bind to the signal, keeping it from binding to the receptor.

thatguybil has the explanation for competitive inhibition correct.  The Km will decrease as concentration of the inhibitor increases, but Vmax will generally not change.\n\nIn the case of uncompetitive inhibition, the apparent Vmax and Km will both decrease as the concentration of inhibitor increases.  Unlike noncompetitive inhibitors, which bind both the enzyme and the ezyme-substrate complex, uncompetitive inhibitors bind only to the enzyme-substrate complex.

This is more of an issue in eukaryotes where there is a lag time between DNA transcriptino and mRNA translation.  One reason that mRNA doesn't hang around in the cell is that it serves no purpose for the cell...mRNA is pretty much useless until it is translated.  Also, mRNA that is about to be translated is modified with a 5' cap and a 3' poly-A tail.  If the mRNA doesn't get to the ribosome (and therefore doesn't undergo these modifications) it is highly susceptible to 5'-3' exonucleases and some endonucleases (depending on the organism).

The lysogenic cycle takes more energy, and likely takes longer as well.

variations matter greatly in interpreting data.  Something might seem like it is returning significantly different results than the control but stat evaluation may show that the variations are minimal at best

Too many to list and explain here, without copying and pasting  --and why should I do all your uni work for you? ;-)\n\nI will recommend a couple of good text books through.  Well worth a purchase or just get them on loan from your library...\n\nAlberts et al, Molecular Biology of the Cell\nStryer, Biochemistry\n\nIt's been since I bought mine.  Think I got editions 2 & 7 back in 1996 and I know both have been updated a couple of times since.  These are still a GREAT basic resourse for this sort of question.

All answers are correct. The primary aminoacid sequence is changed which may have implications for the structure and funtion of the protein

Enzymes work slowly at low temperatures, e.g. at refrigerator temperatures.\nEnzymes work faster and faster as the temperature increases up to a point - this is usually body temperature - salivary amylase (and our other enzymes) are designed to work best at this temperature.\nEnzymes controlled reactions will slow down beyond this optimal temperature because, since they are protein molecules, they will denature (scramble - exactly like like scrambled egg).\nTo see this in graph form have a look at this page:
