Which statement below describes a feature that is shared between kinesin and dynein? a. Both proteins "walk" towards the (+) end
of a microtubule b. Both proteins "walk" towards the (-) end of a microtubulec. Both proteins bind ATP and F-actin Both proteins function in the positioning of organelles inside a cell d. Both proteins associate with the same regulatory factors
*C option is not mentioned* there is a flaw in the question
Explanation:
Two families of motor proteins, kinesin and dynein, transport membrane-bounded vesicles, proteins, and organelles along microtubules. Nearly all kinesins move cargo toward the (+) end of microtubules (anterograde transport), whereas dyneins transport cargo toward the (−) end (retrograde transport).While
both the protiens have globular ATP-binding heads that function as the motor domain and interact with the microtubules.
The job of catalysts in chemical reactions is to make the reaction go faster by lowering the amount of energy needed to activate the reaction. If less energy is needed for the reaction to occur, then the reaction can go faster because a large energy build-up is not needed.
