So 60,000 molar per second, and we divide it by the total number of enzymes that we have inside our mixture. And what we ultimately get is 600,000 seconds to the negative one. And what this describes is it tells us that a single enzyme and its single active side can basically transform 600,000 substrate molecules into 600,000 product molecules every single second. And this is actually a description of a specific type of enzyme, one of the quickest enzymes found in our body, carbonic anhydrate. So remember, carbonic anhydrates is that enzyme found inside the red blood cells, which essentially allows us to actually transform the non polar carbon dioxide molecule into the polar bicarbonate ion. And that's how we can store the carbon dioxide inside our blood and transport it from the cells and tissues and to the lungs in our body.
