WebHydrogen peroxide is toxic and must be converted to water and oxygen by the enzyme catalase. (5.5.1) 2 H 2 O → c a t a l a s e 2 H 2 O + O 2. Hydrogen peroxide is also commonly used as a household disinfectant. It bubbles when it is applied to cuts and scrapes because catalase is present in the fluids of the broken cells.
WebApr 12, 2024 · The reaction started when the optimum parameters for the highest activity of each enzyme were set (alcalase: 60 °C, pH 8.0; pepsin: 37 °C, pH 2.2; trypsin: 37 °C, pH 8.0). The pH of the solution was maintained by continuously adding 1 M NaOH and 1 M HCl. Aliquots were taken for times of 30, 60, 120, and 180 min replacing their volume with ...
WebPepsin is found in the stomach, amylase in the saliva, and phosphatase in the liver. Synthesis: How does pH affect the activity of enzymes?
