The effect of adding a catalyst on reaction rate

1 answer

An everyday example of the effect of adding a catalyst on reaction rate is the use of enzymes in biological systems. Enzymes are biological catalysts that speed up chemical reactions in living organisms. For example, the enzyme amylase helps to break down starch into sugar in your saliva, which is essential for the digestion process. By catalyzing this reaction, amylase increases the rate at which starch is broken down, making it possible for your body to efficiently extract nutrients from food. Without the enzyme, this process would be much slower and less efficient.
