WebTo catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. These molecules are the enzyme's substrates. In some reactions, one substrate is broken down into multiple products. In others, … WebNov 16, 2024 · An enzyme exhibits maximum activity over the narrow pH range in which a molecule exists in its properly charged form. The median value of this pH range is called the optimum pH of the enzyme (part (b) of Figure 14.7.2 ).
WebPolyphenol oxidase (PPO) enzyme is a major enzyme which is responsible for the browning reaction in damaged plant tissues and fruits [1,2,3]. This enzyme catalyzes two distinct reactions involving molecular oxygen [4,5]: (i) the o-hydroxylation of monophenol (monopheolase activity) and (ii) the oxidation of o-diphenol to o-quinones (diphenolase ...
