Motor proteins provide for molecular transport of materials in cells by interacting with what types of cellular structures

Motor proteins provide for molecular transport of materials in cells by interacting with CYTOSKELETAL STRUCTURES.
Cytoskeletal structures refers to those structures in the cells that provide basis for movement from one part of the cell to another.
Motor protein work together with cytoskeletal structures to carry different type of materials from one point of the cell to another point.

Explanation:The author develops the theme of my Module One short story by describing how the character acts, the setting which is prison, and how he doesn't trust anyone in the prison. Condensed Milk shows how the main character usually acts deceiving and how he is working in horrible conditions that cause him to starve. (That creates a motive and evidence of actions that he has done before) the story also shows that he is in prison. (This shows us that he did something bad and now is getting consequences) In addition, he doesn't trust anyone, so he was able to analyze the situation and make the best out of it. He got 2 cans of condensed milk instead of risking his life.
