How do you change the concentration of the substrate where the substrate is milk and the enzyme is renin?

Answer 1

i just did this experiment in class today. what you need to do is add water to the milk. but you have to keep the same amount of milk in all of them. this is if you are testing the effect of substrate concentration on renin. so you have one experiment with 8ml of milk and then one with 6 ml of milk and 2 ml of water and 4 ml of mik and 4ml of water and so on ... be carefful to stir the solution a bit i hope this helps
