Re: The Effect of Changing the Concentration of an Enzyme... by BioWizard on April 6th, 2010, 2:38 am. Obviously in this case, the increased concentration of enzyme results in an increased rate of reaction, up to a given point when all of the active sites of the enzyme are used up. That statement is phrased weird. The more enzyme you add, the more sites there is. Thus, as you add enzyme, you increase the concentration of available sites, not the other way around. I suppose what you meant to say is up to a given point where all the substrate molecules are bound to enzyme.
1 Vinyl siding is relatively low-cost, low-maintenance and easy to install. 2  It costs less than $1 a square foot for a do-it-yourself project, or $1,000-$1,250 for 1,250 exterior square feet.3  Having it professionally installed runs $2-$7 a square foot, or $2,500-$8,750 for 1,250 square feet. It costs less than $1 a square foot for a do-it-yourself project, or $1,000-$1,250 for 1,250 exterior square feet. 2  Having it professionally installed runs $2-$7 a square foot, or $2,500-$8,750 for 1,250 square feet. 3  Aluminum siding is fireproof and impervious to termites, and can last 35-40 years.
1 The average vinyl siding cost is $2 to $12 per square foot installed. 2  For a typical home with 1,500 exterior square feet, that works out to a total cost of $3,000 to $18,000.inyl Siding Average Costs. 1  The average vinyl siding cost is $2 to $12 per square foot installed. 2  Trim pieces will raise the overall cost a bit because they are more labor-intensive, as will soffit, fascia, and window channels if they are not included in the estimate. 3  Removing old siding might cost $1,500 to $3,500.
