Which of the Following Motor Proteins is Correctly Paired with Its

Question

Which of the following motor proteins is correctly paired with its primary function?
A)myosin V: muscle contraction
B)myosin II: cargo transport
C)cytoplasmic dynein: bending of cilia or flagella
D)axonemal dynein: cargo transport
E)none of the above

Accepted Answer

Myosin V is primarily involved in cargo transport within cells, not muscle contraction. Myosin II is the motor protein involved in muscle contraction. Cytoplasmic dynein is involved in cargo transport towards the minus end of microtubules, not specifically in bending cilia or flagella. Axonemal dynein is indeed involved in the bending of cilia and flagella, not cargo transport. Therefore, none of the pairs provided are correctly matched with their primary functions.
