WebSo I know a hill coefficient greater than 1 is positive cooperatively. Hill coefficient = 1 no coop . Hill coefficient less than 1 = negative coop . My question has to deal with the shape of the curve. I know that the shape of a positive coop enzyme is sigmoidal. What about for negative coop? Thanks in advance! WebThe simplest definition of a coefficient is that it is the number in front of the variable(s) in a term. For example, consider the polynomial: 5x^2 + 3x - 8 The 5 is the coefficient for the term 5x^2. The 3 is the coefficient for the term 3x. Hope this helps.
