Motor Proteins Require Energy in the Form of ATP

question 28

Multiple Choice

Motor proteins require energy in the form of ATP. ATP hydrolysis results in a conformational change that allows the protein to move along microtubular tracks (pathways) . What structural component of the motor protein contains the ATP binding site and, therefore, changes shape to enable movement?

• A) the portion of the molecule that binds to the vesicle being transported
• B) the stalk
• C) the portion of the molecule that binds to the microtubular track along which the vesicle is being transported
• D) a location midway between the vesicle binding site and the portion of the molecule that binds to microtubular tracks
