please do part D and E. explain!

2. Below is an alpha helix from hexokinase. Only the backbone atoms are shown, but none of the hydrogens. The oxygens and nitrogens are shaded darker. The sequence of this alpha helix is: I-S-K-A-R-Q-V-A-D-A-M-- A). In the structure show where 1 example of the main interaction that stabilizes this structure would occur by drawing a line between the atoms that interact. If the interaction involves charges draw an arrow pointing from the positive to the negative charge. B). In the box draw an example of the interaction you indicated in part A, showing the specific groups that would form the interaction. C). On the diagram draw in where the side chain of Ala4 would be D). This helix is part of the tertiary structure of hexokinase. In the box with the alpha helix, draw an example of the most likely interaction the side chain you drew in part C would be making in the tertiary structure of the protein. If the interaction involves charges draw an arrow pointing from where a positive could be to where a negative charge could be. E). For each of the interactions you drew briefly explain whether or not you drew an arrow. Justify your decision. Be sure to clearly state which interaction you are referring to in each justification. (MAX: 2 sentences per interaction)
