Because enzymes are specific and speed only one type of reaction.
prevent the substrate from binding the enzyme's active site
It means that an enzyme will only work on one specific substrate at a time, because no meaningful biochemical activity can occur without their absolute specificity.We are talking about 30,000 bio-enzymatically controlled Biochemical reactions.In the Chem Lab a product yield of 60 percent is a huge achievement.In the Body anything less than a 100 percent yieldwould swiftly result in the Cell being overwhelmed by the useless by-products of these 30,000 biochemical Reactions.
The allosteric enzyme curve shows how enzyme activity changes when regulatory molecules bind to the enzyme. This curve demonstrates that the binding of regulatory molecules can either increase or decrease enzyme activity, depending on the specific enzyme and regulatory molecule involved.
Hydrochloric acid can denature enzymes by disrupting their structure and altering their active site. This can impact the enzyme's ability to catalyze chemical reactions effectively, potentially leading to a decrease or loss of enzyme activity.
To determine the optimum pH of an enzyme, you can conduct experiments at different pH levels and measure the enzyme activity. The pH at which the enzyme shows the highest activity is considered its optimum pH.
Shape of an enzyme specifically shape of its active site determines enzyme specificity .
Enzyme specificity is mainly determined by the active site structure and the interactions between the enzyme and its substrate. The shape, charge, and chemical properties of the active site are crucial in determining which substrates can bind to the enzyme and undergo a catalyzed reaction. Additionally, enzymes undergo conformational changes upon substrate binding to further enhance specificity.
prevent the substrate from binding the enzyme's active site
The size of the enzyme's active site would not contribute significantly to substrate specificity. Substrate specificity is typically determined by the shape, charge, and chemical properties of the active site that can properly bind to the substrate.
Increasing enzyme concentration increases the number of collisions between the enzyme molecules and the substrate molecules. This increases the number of successful collisions and the number of enzyme-substrate complexes. Therefore the reaction rate is increased as well and enzyme activity is promoted.
each enzyme has a specific substrate to which it binds through a definite active site and any other enzyme can not bind to it
Enzyme specificity .
enzyme specificity
What an enzyme does is based on its shape, therefore you would have to change it on a molecular level in order to alter its job.
amino acids, which contribute to their unique structures and functions. The specific sequence of amino acids in an enzyme is determined by the gene that codes for it. Changes in the amino acid sequence can affect the enzyme's activity and specificity.
Physical activity can alter the shape of enzyme which can cause damage or may the enzyme become inactive
Enzyme activators like cofactors or substrates can switch on enzyme activity by binding to the enzyme and promoting its function. Conversely, inhibitors can switch off or reduce enzyme activity by binding to the enzyme and preventing its normal function.
