Lock and key model应该很好理解,substrate are exactly complimentary to enzyme active site.他们是一个完美的契合结构,像钥匙和锁一样。 Induced fit mode是指当substrate结合到active site后,enzyme will change its structure,使得substrate和active site的结合...

The active site region is a hotspot for engineering plastic-degradingenzymesbecause the interaction between theenzyme active siteand substrate is a critical factor dictating the efficiency of plasticdepolymerization[22,59]. A common strategy is to create a wider opening of the active site to increase...
2.5.U1 Enzymes have an active site to which specific substrates bind. 2.5.U2 Enzyme catalysis involves molecular motion and the collision of substrates with the active site. 酶促反应中,反应物称为底物(substrate),生成物称为产物(product)。酶的作用就是把底物结合到一个特殊的结构中,这个结构叫活性位...
The active site of an enzyme(A) is formed only after addition of a specific substrate(B) is directly involved in binding of allosteric inhibitors(C) resides in a few adjacent amino acid residues in the primary sequence of thepolypeptide chain...
thereby deforming its active site and preventing it from reacting with its substrate. This latter type of noncompetitive inhibition is calledallosteric inhibition; the place where the inhibitor binds to the enzyme is called the allosteric site. Frequently, an end-product of a metabolic pathway serves...
the binding capacity within substrate and active site of the enzyme (Km), as well as the substrate intake (Kcat). Enzyme reactions take place at punctual pH, known as optimum, where the highest enzyme activity (Vmax) is presented, and above or below it, the reaction rate decreased (Fig....
(d) Inhibition of succinic dehydrogenase by malonate is an example of competitive inhibition. This is reversible reaction. On increasing the substrate (succinate) concentration the effect of inhibitor is removed and V("max") remain same.
7.6.1 State that metabolic pathways consist of chains and cycles of enzyme- catalysed reactions. Metabolic pathways consist of chains and cycles of enzyme-catalysed reactions. 7.6.2 Describe the induced-fit model. Initially the substrate does not fit perfectly into the active site of the enzyme....
