What Are the Two Ways to Inhibit Enzyme Activity?

WebbFor example, the optimum pH of an enzyme that works in the acidic environment of the human stomach is lower than that of an enzyme that works in a neutral environment of human blood. When the pH value deviates from the ideal conditions, the activity of the enzyme slows down and then stops. http://www.chem4kids.com/files/bio_enzymes2.html Webb1. The enzyme and the substrate are in the same area. Some situations have more than one substrate molecule that the enzyme will change. 2. The enzyme grabs on to the substrate at a special area called the active site. The combination is called the enzyme/substrate complex. Enzymes are very, very specific and don't just grab on to any … incorp resident agent
