Determining Enzyme Activity
Enzyme activity is like a cooking show: the more enzymes (chefs) you have, the faster the dish (reaction) will be prepared. Just like you can’t measure how much you cooked without weighing the food, you can’t measure how much an enzyme did its job without some calculations.
To calculate enzyme activity, you need to know the rate of reaction. This is how much substrate (the food) is turned into product (the dish) per unit of time. You can use different units to express it, like micromoles per minute (µmol/min) or units per liter per second (U/L/s). Enzyme activity is typically measured in units (U). One unit is defined as the amount of enzyme that catalyzes the conversion of 1 micromole of substrate per minute under specific conditions, usually at 25°C and pH 7.
Imagine you’re measuring the activity of a lipase enzyme, which breaks down fats. You’ll set up a reaction in a test tube, add lipase, and measure how much fat is broken down over time.
