Question

question 15
movement of vesicles within the cell depends on what cellular structures?
○ microtubules and motor proteins
○ actin filaments and microtubles
○ actin filaments and moto proteins
○ centrioles and motor proteins

Explanation:

To determine the correct answer, we analyze each option:

• Microtubules are part of the cytoskeleton and provide tracks for motor proteins (like kinesin and dynein) to move vesicles within the cell.
• Actin filaments are more involved in cell shape, muscle contraction, and smaller - scale movements, not the main tracks for vesicle transport.
• “Moto proteins” is a misspelling, and even if it were “motor proteins”, actin filaments are not the primary structure for vesicle movement.
• Centrioles are involved in cell division (organizing microtubules during mitosis/meiosis) and not in vesicle transport.

So the correct option is the one with microtubules and motor proteins.

Answer:

A. microtubules and motor proteins
