Match each function with the correct cytoskeletal structure

Match each function with the correct cytoskeletal structure.

Solution

The fucntions mentioned above are all related to different types of motor proteins. It can be difficult to seperated the functions for different types of proteins; however in this answer I have tried to match each structure to its main function.

Motor proteins are molecules that move along the substrate surface in an eukaryotic cell by repeated hydrolysis of ATP. Motor proteins can be of 2 types-

The main function of motor proteins is to actively transport cytoplasmic proteins and vesicles.

So, the answer is: Motor proteins - use ATP to move vesicles within cell. They can also use the ATP to bend filaments.

Microtubules are fibrous shafts of tubulin which gives support and shape to the cell forming the cytoskeleton in eukaryotic celss. They can also assist in intracellular transport of organelles in the cell. Microtubules in the centrioles help in cell division by connecting to chromosomes, help the chromosomes complete their first division, and then move the new chromosomes to the new daughter cells.
Microtubules can combinecan be involved in the formation of cilia and flagella for cell movement.

So, the answer is: Microtubules- involved in chromosome sorting during mitosis. Strong structural protein that maintains cell shape.

Interrmediate filaments are a type of cytoskeletal fiber. Their most important function is to provide mechanical support to plasma membrane.

So, the answer is: Interrmediate filaments- Dynamic protein used to support plasma membrane

Actin works along with another muscle protein myosin for muscular contraction and relaxation. Other than that they can provide cytoskeletal support and assist in cell division.

So, the answer is: Actin- structural protein used in muscle contraction.
