A further increase in length may reduce catalytic turnover by slowing the rate of product release (see section on Kinetic Properties). It may also reduce substrate specificity by slowing the rate of release of a mismatched substrate. For applications in which substrate specificity is not critical,...
What are the 2 basic steps of enzyme action? 1) Enzyme bind to active site2) Conversion of initial compound to productE + S > ES > E + P How do enzymes increase reaction rate? Lowering activation energy! What are the advantages and disadvantages of enzymes? Advantage:Reduce costSpecificI...
提高反应物的浓度(增加碰撞collision概率)或是使用无机催化剂(inorganic catalysts),而在生物体中,许多的化学反应都是在比较温和的条件下自发的进行,并且是在需要的时候进行,这得益于酶(biological catalyst, increase the rate by lowering the activation energy*)的参与,让反应物在浓度很低的时候都能够进行反应。
They can increase the reaction rate for a given reaction by a thousand-fold or more.
Enzymes are proteins, or occasionally RNA, found in cells that act as biological catalysts. Their mode of action is to lower the activation energy of the reaction by forming an enzyme-substrate complex, which is a more stable intermediate than would be formed, were the enzyme not present. Th...
How is enzyme activity regulated by the cell? Is enzyme activity affected by pH levels? Why and how? How does an enzyme work to increase the rate of a reaction? How does an enzyme work to catalyze a reaction? Does pH affect enzyme activity?
However, Vmax is unchanged because, with enough substrate concentration, the reaction can still complete. The graph plot of enzyme activity against substrate concentration would be shifted to the right due to the increase of the Km, whilst the Lineweaver-Burke plot would be steeper when compared ...

end result of reaction as enzymes increase, the reaction rate what? the reaction rate increases, more enzymes=more frequently collide with substate when do high enzyme concentration reaction rates level off? when the substrate becomes the limiting factor and not all the enzyme molecules can find ...
Effect of (A) pH, (B) temperature, (C) substrate concentration, and (D) enzyme concentration on enzyme-catalyzed reaction. 4.2 Temperature The temperature increases the rate of any chemical reactions, including the enzyme-catalyzed reactions, with an increase of two to three times every 10°C...
