NettetHowever, at some point you will reach a substrate concentration at which the enzyme gets saturated and becomes the limiting factor. In this case you have to add more enzyme to speed up the reaction again. Many other factors affect the activity of enzymes as well. Most enzymes only function under optimal environmental conditions. Nettet1. apr. 2011 · The greater the substrate concentration, the higher the rate of reaction: As the number of substrate molecules increases, the likelihood of enzyme-substrate …
