Answer 2

carbs and lipids!

Answer 3

Lipids, definitely. Lipids are fats and we know fats store energy--they also make up the lipid bilayer of cells.

Proteins contribute to structures, so I would select that too. Proteins can also be used for energy storage.

Carbohydrates I think are used primarily (and only?) for energy storage.
Proteins and lipids for sure, you should google carbohydrate structures. I'm not sure a sugar would make much of anything, though.

Answer 4

Proteins are used in the structure of many things, though. I would argue that.

Thank you both! :d
