Hi everyone !! Could someone help me understand the graphics regarding this subject? i have this graph where the control curve has a sigmoid behavior and the other two have an allosteric effector (+) and (-) how could this look on a Hill chart? I’m confused about what curve should have a slope equal to 1 and how the others would look. thank you ! Please help me pass my exam P.S: forgive my english, i don’t speak it in a native way
