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...

van der Waals correct answer: -weakest (short lives) but lots could strengthen the bond -furthest distance -form as a result of hydrophobic interactions -strength depends on the size of the atoms and the distance between them -cannot be closer than the Van der Waals contact distance or else positively charged nuclei will repel each other (energy= 0) Proteins correct answer: main action molecule of the cell (Most chemical processes of the body are carried out by proteins) -classified in...

The dipole moment in a water molecule Which statement about hydrogen bonds is NOT true? A) Hydrogen bonds account for the anomalously high boiling point of water. B) In liquid water, the average water molecule forms hydrogen bonds with three to four other water molecules. C) Individual hydrogen bonds are much weaker than covalent bonds. D) Individual hydrogen bonds in liquid water exist for many seconds and sometimes for minutes. E) The strength of a hydrogen bond depends on the linearit...

Electronegativity is larger/smaller with a greater number of electron shells. - correct answer smaller Electronegativity is larger/smaller with a greater proton number in a given period (horizontal row). - correct answer larger What is wrong, if anything, with the following statement: "When NaCl is dissolved in water, the water molecules closest to the ions will tend to preferentially orient themselves so that their oxygen atoms can interact electrostatically with the chloride ions...

How is a tertiary structure held together? - correct answer the hydrophobic effect, Hydrogen bonds, and ion-ion interactions What would be the consequence of changing an amino acid that helps to hold together tertiary structure? - correct answer Changing the amino acid would change the structure therefore making it non-functional. How is a quarternary structure held together? - correct answer By the hydrophobic effect, hydrogen bonding, ion-ion interactions and Van der Waals interact...
