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...
When an enzyme binds to its substrate, it undergoes a conformational change or temporary change in shape. However, once the product(s) is released, the enzyme will regain its original shape. This enzyme-substrate complex diagram demonstrates how a substrate binds to an enzyme, is converted ...
Alters the active site of the enzyme Enzymes influence chemical reactions in living systems by 1. providing the substrate required for the reaction to occur 2. affecting the rate at which reactions occur 3. absorbing water released when polymers are formed 4. combining with excess hydrogen to for...

Diagram to show (A) enzyme–substrate complex, (B) competitive, (C) noncompetitive, and (D) uncompetitive inhibitors. Noncompetitive inhibitors bind to the allosteric sites (other than active site) and deform the structure of the enzyme (Fig. 34.3C). This change in shape does not allow ...

When the enzyme and its substrate come together, at a place on the enzyme called the active site, the substrate is modified, for example by combining two different substrate molecules into a single molecule. The enzyme remains unchanged, breaks away, and is free to perform its chemical magic ...

The gel matrix should have an efficient conductivity and must be permeable to substrate and product to ensure continuous transformation. Compared with the covalent bonding, this method is simpler and leads to preserve intrinsic properties of enzyme on the electrode surface for a longer time. However...
