The simplest and the original assumption about step size for molecular motors was that as the motor protein walked along the actin or microtubule polymer it would step__________.
A)10 nm for every ATP that was hydrolyzed whether it was traveling along actin or tubulin
B)the distance of one tubulin dimer or actin subunit for every 2 ATPs that were hydrolyzed
C)the distance of three tubulin dimers or actin subunits for every ATP that was hydrolyzed
D)random distances along the cytoskeletal polymer for every ATP that was hydrolyzed
E)the distance of one tubulin dimer or actin subunit for every ATP that was hydrolyzed

Question

Quizplus · Accepted Answer

The original assumption about step size for molecular motors was that the motor protein would step the distance of one tubulin dimer or actin subunit for every ATP that was hydrolyzed. This option is only mentioned once and is the correct answer. The other options, namely A, B, C, and D, are not mentioned as original assumptions about step size for molecular motors.
