Question

Axonemal dyneins are

A) associated with organelle movement.
B) associated with cilia and flagella.
C) monomeric myosin-like proteins.
D) responsible for axonal anterograde transport.
E) All of the above are correct.

Answer 1

Axonemal dyneins are motor proteins associated with the movement of cilia and flagella, not with organelle movement, anterograde axonal transport, or acting as monomeric myosin-like proteins.

Step-by-step explanation:

The movement of cilia and flagella is enabled by dynein arms walking along microtubules in the axoneme structure. Therefore, option B) associated with cilia and flagella is the correct answer for this question. Axonemal dyneins are associated with cilia and flagella. They are part of the motor proteins that interact with microtubules within the axonemes, which are the core structures of cilia and flagella. As motor proteins, dyneins use ATP to move along microtubules, which allows for the bending and movement of cilia and flagella, crucial for cell motility, the feeding process, and sensation in certain cells.
