    00:02 In this lecture on membranes, we'll begin to put our knowledge of macromolecules together to form a membrane that can communicate with the outside world of the cell.

    00:12 As well as explore internal components of the cell that maintain structure.

    00:18 So by the end of this lecture, you should be able to explain how proteins, lipids and carbohydrates are involved in the structure of the cell membrane.

    00:28 As well as explain how fluidity is maintained in the cell membrane. It's not a static unit.

    00:36 Then we'll be able to describe the roles of each of the three types of cytoskeletal elements in maintaining cell's shapes and transporting molecules throughout the cell.

    00:46 And in addition, you'll be able to explain how cells stick together to associate and form tissues.
