And so that should basically correspond to higher values in these two boxes. So let's calculate what the specific value is for step C. So we basically take the enzyme activity of that specific sample, right, and we divide it by the total protein because as always, specific activity is this divided by this. So this divided by this basically give us gives us. So we cross out the three zeros and we get 125 divided by one. And that leaves us with 125. Now, what about the purification level?
