Slow down or stop the activity of an enzyme
WebbThe browning can be slowed down by preventing the enzyme from working properly. Lemon juice contains an acid which can stop enzymes working properly as enzymes often work best at a certain pH. Water and sugar, in jam for example, stops oxygen in the air getting to the enzymes and prevents the browning.

Webb16 maj 2024 · Elaborate chemical structures called enzymes control the vast majority of chemical reactions within living things. As such, enzymes have incredible diversity in form and function. Every individual enzyme has a specific optimal pH. Outside of their ideal pH range, enzymes may slow down or stop working entirely. http://www.chem4kids.com/files/bio_enzymes2.html
