WebApr 11, 2024 · The enzyme molecules were readily combined with the substrate, which ultimately manifested itself as an increase in enzyme activity (Kubo et al., 2024). These were summarized as the nonthermal effect of MWs causing a change in the conformation of the enzyme molecules that exposed the catalytic site of the enzyme. WebIf the active site were changed, possibly by a large change in temperature or pH, the enzyme would most likely not be able to catalyze the same reactions. This is because temperature and pH can denature (or change) and enzyme's shape and therefore … Enzymes are not reactants and are not used up during the reaction. Once an … birdhouse picture frame
