WebFeb 14, 2024 · The activity of many enzymes is strongly influenced by the pH of the reaction milieu. Although some enzymes exhibit activity in a broad range of pH [], many show maximal activity at a narrow pH range [], referred to as the pH optimum.The pH optimum is a key parameter that must be determined accurately as enzymatic activity, behavior and/or … WebThe optimum temperature for most enzymes is about 98.6 degrees Fahrenheit (37 degrees Celsius). What is the optimal pH at which pepsin functions? The digestive power of pepsin is greatest at the acidity of normal gastric juice (pH 1.52.5). In the intestine the gastric acids are neutralized (pH 7), and pepsin is no longer effective.

WebThe preferred temperature for catalase falls between the ranges of thirty five to fifty degrees Celsius (4). Temperatures that are too high denature the enzyme and halt the enzyme’s activity (2). Catalase denatures starts to denature at fifty five degrees Celsius (2). Reactions in the human body produce hydrogen peroxide as a product (1). WebVery high temperatures (for animal enzymes, above 40 40 ^ {\circ}\text C ∘C or 104 104 ^ {\circ}\text F ∘F ) may cause an enzyme to denature, losing its shape and activity. ^2 2 pH. pH can also affect enzyme function. Active site amino acid residues often have acidic or basic properties that are important for catalysis.
