Factors affecting Enzyme Activity

In nature, organisms adjust the conditions of their enzymes to produce anOptimum rate of reaction, where necessary, or they may have enzymes which are adapted to fun ...

... Active site = the fold/pocket where an enzyme’s substrate fits into. An enzyme acts only on a specific substrate because only that substrate fits into its active site. Three steps of enzyme activity: 1. A substrate attaches to an enzyme’s active site. 2. The enzyme reduces the activation energy of t ...

... Enzymes are agents that change the rate of reaction without being changed themselves. The active site on an enzyme is open to a substrate and will change it by carrying out the reaction. Competitive inhibitors sometimes get in the way by either blocking or changing the shape of the active site on an ...

Testing the activity of enzymes
... The vast majority of enzymes are proteins. Their function is directly related to their very precise 3-D shape (configuration). If that 3-D shape is altered, the enzyme will not function. The enzyme and its substrate must fit together like a lock and key. In some cases, cells control the activity of ...
