Document Summary
Learning objectives & review questions - lecture 15. Explain how kinesins and dyneins function as motor proteins within a cell. Kinesins: move contents in the anterograde direction, center to out, Dyneins: move contents in the retrograde direction, out to center, Explain how the movement of cilia and flagella relates to their structure and function. Primary cilium: non-motile cilium, mainly receptor cilium with sensory functions. It refers to the movement of the microtubule associated motor proteins. Identify the two types of microtubule-associated motor proteins and discuss their direction of movement. Movement of material from the golgi to the plasma membrane: Movement of endocytosed vesicles from the plasma membrane to early endosomes. General movement of material from peripheral locations in the cell (near the plasma membrane) toward the center of the cell. Movement of a vesicle containing a membrane receptor to be recycled, from the endosome back to the cell membrane.
