Enzymes are biocatalysts which increase the rate of biochemical reactions without undergoing any change themselves. It binds to the substrate forming the enzyme substrate complex and forming the product. The acceleration factor of enzymes is the factor by which the enzyme increases the rate of the reaction.

Pepsin and trypsin are enzymes involved in the breakdown of proteins in the stomach and the small intestine respectively. Enzymes function best at a particular pH called the optimum pH. Pepsin is found in the stomach with an acidic environment and function best at a pH range of 2-3. Small intestine has a pH between 7-8 and Trypsin secreted by the pancreas into the small intestine functions best at a neutral or slightly alkaline pH of 7-8.  Thus, the catalytic activity of the enzymes is maximum at its optimum pH.

Virty [35]

<span>The answer is B. 72.25 percent.

The Hardy-Weinberg principle can be used:</span>

<em>p² + 2pq + q² = 1 </em>and <em>p + q = 1</em>

where <em>p</em> and <em>q</em> are the frequencies of the alleles, and <em>p²</em>, <em>q²</em> and <em>2pq</em> are the frequencies of the genotypes.

<span>The <em>p</em> allele (<em>q</em>) is found in 15% of the population:
q = 15% = 15/100
Thus, q = </span><span>0.15

To calculate the <em>P</em> allele frequency (<em>p</em>), the formula <em>p + q = 1</em> can be used:
If p + q = 1, then p = 1 - q
p = 1 - 0.15
Thus, </span><span>p = 0.85

Knowing the frequency of the <em>P</em> allele (<em>p</em>), it is easy to determine the frequency of the <em>PP </em>genotype (<em>p²</em>):
p² = 0.85² = 0.7225

Expressed in percentage, p² = 72.25%.</span>
