Question

see if you can identify the key components of the vesicle transport system in the screenshot from the kinesin walking model. choose all statements that are correct. the red \studs\ sticking out of the blue blob are \zip code\ proteins. the red molecule between the big blue blob and the long, tubular - shaped structure is kinesin. the long tubular - shaped structures are actin microfilaments. squid are marine animals and have a huge nerve cell that runs the length of their body. researchers have been able to study vesicle transport by opening up these cells, squeezing out the contents, focusing videomicroscopes on microtubules that run the length of the cell, and recording how vesicles move in real time. the next several questions ask you to make predictions about this system. suppose you added vesicles to the system that lacked zip code proteins in their membrane. predict what would happen. the vesicles would not be able to move, because kinesin would not attach to microtubules properly. did you fully understand the concept covered in this section?

Explanation:

In the kinesin - walking model, kinesin is the motor protein that moves along microtubules to transport vesicles. Microtubules are the long, tubular - shaped structures, not actin microfilaments. "Zip - code" proteins help target vesicles to specific locations. Without zip - code proteins, vesicles may not be properly targeted but kinesin can still attach to microtubules and move.

Answer:

The red molecule between the big blue blob and the long, tubular - shaped structure is kinesin.
