Spectrophotometry is a method that helps us measure how enzymes work by looking at changes in light absorbance. This means we can see how much light is absorbed when a substance is used up or made during a reaction. Here are some important points about this process:
How It Works: When enzymes react with their substrates, they change the amount of colored substances in the solution. We can measure these changes at specific light wavelengths.
Data Insights: For example, in enzyme tests, the usual range for how sensitive we are to changes in substrate concentrations is about 0.1 to 1.0 mM. This helps us understand the enzyme activity better.
Calculating Activity: To figure out how active an enzyme is, we can use the formula:
V = ΔA / (ε * l)
Here, ΔA is the change in absorbance, ε is how much light the substance can absorb, and l is the distance the light travels through the sample.
This method is great because it lets us watch enzymatic reactions in real time. We can see how enzymes change substances and measure their activity as it happens!
