Discuss the following forces that are involved in the binding of substrates to enzyme: 1. electrostatic interactions 2. hydrogen bonds 3. van der Waals forces 4. hydrophobic forces Correct Answer-All of these interactions contribute to binding energy, increasing specificity of the substrate to enzyme binding. Each of these interactions need to be close in order to get significant binding (especially van der Waals, upon which this relies on). These reactions do not need to be as precise, just...
